In the 1980's the CIA armed the Islamic mujahideen in Afghanistan to fight the Soviets.
That action tturned out to be the catalyst of a disasterous 25 years for the USA, the mid-East and Europe.
Osama bin Laden, a wealthy Saudi, was a prominent organizer and financier of foreign volunteers for the mujaheddin in Afghanistan.
When the Soviets withdrew, some of the mujahideen morphed into the Taliban and embarked on a reign of militant Islamic jihadi terror.
Osama bin Laden went on to found Al-Qaeda.
In 2001 Osama bin Laden and al-Qaeda carried out the 9/11 attacks on the World Trade Center and the Pentagon.
And here we are after 15 years of fighting in Afghanistan:
Obama is arming al-Qaeda in Syria in hopes of taking Assad down and installing a hard line Islamic regime.
