Who do you think ISIS received all its funding, arming, and training from?
Money and arms - from SA. Training from other sunnis in the iraqi army.
The money and weapons didn't just magically appear. It was all about 'Regime Changing' Assad. Just more bloody Blow Back. Time to disengage from the Middle East. We've done enough damage there.
As for assad, are you so stupid and ignorant that you were not aware he was arming/funding anti-US fighters/terrorists in syria and allowing them to use syria as a base from which to attack US forces?
US mulling military options against Syria
"By now it has become clear that Damascus has opted out of its military accord with the Americans. The volume of fighting forces and war materiel crossing from Syria to Iraq has increased rather than diminished, and armed bands of tribesmen, among whom Iraqi insurgents, al Qaeda and Hizballah terrorists mingle, have expanded their control of broad regions on the Iraqi side of the border and aggressively attack any American force or vehicle venturing on their turf. Tribes dominating the border region are on the Iraqi insurgents’ payroll, receiving large weekly payments from Iraqi Baath headquarters in Damascus.
The Damascus center is the hub of the 4,000 ex-party leaders and army chiefs living in Syria. It awards the tribes a bonus for every attack they mount against American or Iraqi forces in the border vicinity, as well as a rake-off for every illegal transfer of weapons or explosives. Syrian regime high-ups, top military brass and officers stationed on the border also get their share of the cut.
There have been several unpublicized battles between American and Syrian forces, when Syrian troops intervened to try and prevent the Americans from carrying out a hot pursuit of Iraqi insurgents at the border, Several Syrian soldiers have been killed and captured in these firefights, and senior leaders of the Anaza tribe taken prisoner. Six weeks ago US special-ops forces raided Anaza encampments, uncovering large volumes of weaponry destined for Iraq. They also discovered approximately 10 million dollars in cash and gold coin, and over a hundred terrorists in hiding."
