The Timing Of Terrorism: The Obsessions With Dates
By Christopher C. Harmon

Last month was the black anniversary of September 11, 2001. It has many meanings for us, but was that date, in particular, selected by Al Qaeda? A few suggest there is a link to the last day of the battle in 1683 at the gates of Vienna, a titanic Moslem-Christian struggle for western Europe. Americans might also wonder whether 9/ll—numbers that cry “emergency” to this country—were a clever choice by the terrorists as psychological warfare.

Terrorism is very much about symbols and events—usually political, historical, cultural. Virtually every group has a date, or certain dates, which are sacrosanct. Among the most common: the birth or death date of some hero or martyr; the opening day of an insurrection; the formal founding date of a movement or political party; etc. Some terrorist groups name themselves after an awful date, a tragedy.

But, apparently, the nineteen men sent to their deaths by Khalid Sheik Mohammed were not thinking of a particular date for their attack. We have the meditative letter given to them called “The Last Night” and it was silent on that. Timing seems to have been based on operational needs. It may or may not have been coordinated with the team that murdered celebrated commander Ahmad Shah Masood in Afghanistan two days before airplanes hit American targets. But no Al Qaeda sources confirm special interest in Sept. 11, 1683--and in fact the Battles of Vienna finished the next day, the 12th.

Instead Al Qaeda’s action gave the day its significance. Having made the strike, then they did attach importance to it on anniversaries. Ten years on, in Sept. 2011, their magazine Inspire devoted an issue to recalling “The Greatest Special Operation of All Time.” Later the journal often had “terror timelines” with dates of various Al Qaeda strikes. Such considerations now make each new Sept. 11th a terribly attractive date to the Al Qaeda central group still run by Osama Bin Laden’s former deputy, Ayman al Zawahiri.

Politics & Motivation

First, the reasons to be alert to dates start with how they help us understand a terror group’s political essence and motivation. Second, certain groups may act on or about that day of the calendar. Linking dates with actions or attacks proves terror organizations remember, and it proves their potency: the action says to authorities ‘even when it’s predictable you cannot stop it.’ So the Puerto Rican group Los Macheteros timed an attack—the worst ever against American air forces in the continental U.S.—to mark the birth date of a Puerto Rican independence advocate, Eugenio Maria de Hostos (b. Jan 11, 1839). The attackers in 1981 were one day late but fully successful against Muniz Air National Guard Base, San Juan, P. R. To them, American war planes fit as a symbol of U.S. occupation.

Celebrating Birth Days

Mao Zedong, theorist of guerrilla war and victor in China’s civil war, was born December 26, 1893. That 19th century fact drove more than a few events in the 20th century. The Communist Party of the Philippines-Maoist took care to make its founding date Dec. 26 – in 1968, the 75th anniversary of the Great Helmsman’s birth. Jose Maria Sison was re-founding a staid and small Communist Party, traditionally pro-Soviet; he wanted his cadre fired by “Mao Tse Tung Thought.” His Filipino followers are still fighting democracy a half-century later.

Sison was not the only acolyte to be dazzled by Mao. In distant Peru, in 1980, the morning of Dec. 26 presented to citizens of Lima the spectacle of dogs hung dead from lamp posts, each wearing a placard: “Deng Xiaoping.” The point of this menace was to shame that current Chinese General Secretary for abandoning Maoist economics and deemphasizing class struggle and endless internal revolution. The right day--for such a salute and a shaming--was the 26th of December, 87 years after Mao‘s day of birth. In Lima, this agit-prop against “running dogs” in China and Peru helped open an incredible campaign of insurgent violence around Peru. It was led by Abimael Guzman: professor, purist in Maoism, and visitor to China. When he was finally captured twelve years later his converts in Shining Path had vast “liberated zones” in rural places, in line with Maoist strategy.

In the U.S., a “Revolutionary Communist Party, U.S” founded in 1968 by Bob Avakian affirmed membership in the broader, neo-Maoist “Revolutionary Internationalist Movement.” Shining Path of Peru was also a member; RIM was stretching across national lines; it had chapters from Sri Lanka to Turkey and inspired a vigorous magazine, A World To Win. RIM also did a manifesto in 1993, releasing the text on Dec. 26 because it was Mao’s birthday. Their document argued that Mao was so original and vital that “Today, without Maoism there can be no Marxism-Leninism.”i

Another important date has been May 19, birth day of Ho Chi Minh. That nom de guerre means “he who enlightens.” Ho was a dedicated Communist, working for the Soviets’ Comintern initially and later championing Maoist strategies of warfare to win back South Vietnam. In the American scene, radicals were transfixed by Ho and elevated his name in poster art and chants. Remnants of the Weather Underground Organization linked up with black power militants in 1978 to create a new “May 19 Communist Organization.” That date signaled support for “Uncle Ho.” Perhaps their best-known leader was Assata Shakur/Joanne Chesimard. She was quoted in the Weather Underground manifesto Prairie Fire of when she was still with the “Black Liberation Army.” Shakur was jailed for shooting of New Jersey state troopers. Sprung by revolutionary comrades, she found asylum in Cuba.

May 19th was also the date of the first attack by The Black Liberation Army. For black power advocates May 19 was not just Ho’s birthday but that of the 1925 birth of Malcolm Little, later Malcolm X. A fiery deputy of Louis Farrakhan in the Nation of Islam, Malcolm X’s speeches helped make famous his phrase “by any means necessary,” an open door to all types of political violence beyond “self-defense.” But Malcolm X then made the Haj to Mecca and came back an orthodox Muslim. No less activist or articulate, he quit militancy and Farrakhan’s organization; apparently that rebellion cost him his life. Six years passed and in 1971 BLA made their first attack, selecting the birthday of Malcolm X, May 19. It was a deliberate hit on police officers. BLA would operate for a decade and kill more police than any other terrorist group in American history.ii

Modern eco-terrorists, who say they do not kill but specialize in sabotage, also pay attention to birthdays. Earth First! News, one of those how-to and hortatory magazines, notes birthdays of some terrorists totally outside of the eco milieu—apparently from commitment by journal editors to the idea of revolution. At other times there is a clear link to Earth First policy, as when they remind readers that May 22 is the birthday of anarchist and eco terrorist Ted Kaczynski. Such notices from allies help morale—a ray of recognition breaking into the isolation cell of the Unabomber. Public salute to so violent a man also raises the standard for readers of Earth First! News: The message is to the gentle liberal: ‘reading this on line in your apartment with a cup of tea is not really advancing our movement. We require action and violence to save Wild Nature.’

Publicity for Dates of Uprisings

As the Murrah federal building was reduced to rubble in Oklahoma City in 1995, a smart highway trooper arrested Timothy McVeigh as he drove towards Kansas. When the perpetrator presented his driver’s license, the birthdate (in a false year) showed as April 19—though McVeigh had been born five days later. Why?

April 19 had become a venerable day for the far right. Legends had been building up around it. On that day in 1776, patriots fought at Lexington and Concord, Massachusetts. The far right of the late 20th c. perceived as patriots a violent group called the Covenant, the Sword, and the Arm of the Lord, raided in their compound in Arkansas by federal authorities--on April 19, 1985. And that same day and month in 1993 brought unskilled governmental overreach at the Branch Davidian compound in Waco Texas, where ensuing fire suffocated or burned to death many inside, including children. This was appalling, and it was judged by some to be the crushing of a modest separatist community. Some also linked the date April 19, 1995 to a scheduled execution in Arkansas of the killer of a black state trooper. An event honoring state prisoner and white supremacist, Richard Wayne Snell was to be in Confederate memorial park that day, with the expected crowd to include veterans and Christian Identity adherents. Timothy McVeigh was both. And he had earlier made a pilgrimage to Waco McVeigh believed the Waco “take-down” had been planned by federal authorities based in the Murrah building. So his personal history made it appropriate to choose April 19 to drive his truck bomb into Oklahoma City, killing 168 people in a flash. He hoped to start an anti-federal war and a race war.iii

Insurrectionists of “FALN” were the best-armed and bloodiest of the Puerto Rican separatist organizations. This “Armed Forces of Puerto Rican National Liberation” did dozens of bombings in the eastern U.S. and Chicago. Their first communique came in late October 1974 with attacks in New York City and it read: “These actions have been taken in commemoration of the October 30, 1950 uprising in Puerto Rico against Yanki colonial domination.”

October 1950 had seen Puerto Rican separatists stalking President Harry Truman near the White House. Bumbling by the two assassins, and response by the Secret Service who fought a three-minute gun battle on November first, saved the man from Missouri. Puerto Ricans also shot up the House of Representatives, choosing March 1st, 1954. They had two reasons: the start of an Inter-American Conference in Venezuela; and the date in 1917 when Puerto Ricans were given U.S. citizenship—something this armed minority now rejected. The pistol-carriers injured five people on the floor of Congress; for this they would be named with honors, on the month after 20 years, by the FALN’s October 1974 communique, which demanded their freedom. Ever-committed to symbolism, FALN also staged bombings on an anniversary of that March 1, 1954 attack by other Puerto Ricans on the U.S. House.

The Irish Republican Army annually memorializes an uprising. Its early 20th c. insurrection, initially suppressed, led into civil war that by 1922 did yield an independent 26-county southern republic, Eire. After centuries of British rule, this Easter Uprising of Irish nationalists in Dublin came in 1916. That this happened amidst World War One was no accident: rebels were counting on (a) British preoccupation elsewhere, and (b) German aid. The New York weekly The Irish People explained how Roger Casement worked with German diplomats including Arthur Zimmermann to arrange for a formal aid agreement. When the Irish received that promise it led into planning for an Easter Uprising on April 23, 1916. An Irish Brigade was to be to be formed in Germany and shipped over—although this effort failed. A German arms shipment sailed from Lubeck—but it was scuttled off the Kerry coast when the British Navy caught on.iv These frustrations carried on into Easter when Dubliners did rise…yet saw their leaders arrested.

For such Irish, Easter is politically-saturated. Of course, generally, Easter is always a major religious and cultural celebration for millions of Irish more attentive to the Holy Day and the church than to politics or war. Exemplary of the drive for unification of Ireland by military means is that New York paper The Irish People. In its run of three decades, starting in in 1972, the organ publicized each anniversary of the rising of 1916. Few historical occasions if any rated as much “ink” in the 16-page weekly. Second in its level of interest to Irish militants is an insurrection attempted in 1798 by Wolf Tone. That unusual Irish Protestant became gripped by the dual cause of Irish independence from Britain and his island’s unification. Recognizing an opportunity during conflict between royalist Britain and revolutionary France, Tone persuaded French authorities to invade Ireland to challenge British forces on home grounds. Although their effort disintegrated, there has been a gathering each summer at Tone’s gravesite in Bodenstown, County Kildare, Republic of Ireland. At such memorials, steady adherents are reinforced; young fans are created in conversation with veterans; old prospects of threatening British security in its Irish occupation of the north are “rebooted.”

Marking Founding Dates

The Soviet Union’s founding by Bolsheviks came with the “October Revolution,” dated on our calendars as November 7, 1917. That day was then recalled and elevated by groups all over the world. The first communist party of the Philippines took care to name its founding date as Nov. 7 (1930) due to Comintern influences and the USSR’s political impact. Although the Filipinos’ revitalized communist party of a later generation is explicitly named “Maoist,” they paid respects to the Soviets as their centenary approached (Fall, 2017). Jose Maria Sison, active in foreign exile, published a glowing account of Vladimir Lenin’s achievement in state-founding. The spread offered colored pages on the web site of the International League of People’s Struggle ( ) which Sison founded as an outreach tool of his Maoists.

A hemisphere away, one modern terror group identifies its own founding with unwelcome landings of U.S. troops in the homeland. Puerto Rico saw U.S. troops arrive on July 26, 1898, as the U.S. wrapped up other Caribbean-area fighting of the Spanish-American War. Puerto Ricans would stage independence drives in future decades—sometimes pacific, sometimes violent, always by minorities. Los Macheteros, the machete wielders, took their name from the agricultural tool fundamental to life on the Puerto Rican farms and estates. Three men, including the Cuba-connected Filiberto Ojeda Rios, formed Los Macheteros on July 26 of 1976.
