First, we have, (Emphasis Mine), "Fifty-two American diplomats and citizens were held hostage for 444 days (November 4, 1979, to January 20, 1981), after a group of Iranian students, belonging to the Muslim Student Followers of the Imam's Line, who were supporting the Iranian Revolution, took over the U.S. Embassy in Tehran."

Next we have (from your link), "The initial Soviet deployment of the 40th Army in Afghanistan began on December 24, 1979, under Soviet leader Leonid Brezhnev."
So, 50 days after our embassy falls in Tehran, the Soviets invade Afghanistan. You think that was just a coincidence?
