In 1986, a group of Americans were being held hostage by a terrorist group with ties to Iran. In an attempt to free the hostages, Ronald Reagan secretly sold arms and money to Iran. Much of the money that was received from the trade went to fund the Nicaragua Contra rebels who were in a war with the Sandinista government of Nicaragua. When the scandal broke in the Untied States it became the biggest story in the country, Reagan tried to down play what happened, but never fully recovered.

The attacks on 9/11 by al-Qaeda and Osama Bin Laden brought new attention to international terrorism. All of a sudden, Americans coast to coast wore their American flag pins, ate their freedom fries and couldn't wait to go to war with anyone who looked like a Muslim. What Americans didn't realize was that the same group that attacked the United States on 9/11 was funded by Ronald Reagan in the 1980s. Prepping for a possible war with the Soviet Union, Ronald Reagan spent billions of dollars funding the Islamist mujahidin Freedom Fighters in Afghanistan. With billions of American dollars, weapons and training coming their way, the Taliban and Osama Bin Laden took everything they were given and gave it back to the United States over a decade later in the worst possible way imaginable.
