Groundwork for this madness was laid in August 2 this year when the bozo POTUS signed CAATSA into law.
CAATSA = 'Countering America's Adversaries Through Sanctions Act.'
The IRGC is Iran’s most powerful security institution with plenty of influence on the country's political and economic system as well as the responsibility for preserving the principles of the homegrown revolution. IRGC has played a major role battling terrorists in Syria and Iraq and has been instrumental in achieving many victories. Trump hasn't yet announced whether or not he will sign this ludicrous bill, but it will be close to a miracle if he doesn't. The deadline is October 15. He is expected to decertify JCPOA and specifically target IRGC and Hezbollah with sanctions. The core idea is to weaken Iranian and Hezbollah forces in Syria and consequently put the Syrian army in a tougher situation. Blacklisting IRGC would be the start of another lengthy era of US-Alqaeda cooperation with new buccaneering titles showered on the terror network's sub-groups.
