Anytime I heard from the war hawks (eg. McCain, Graham, Kerry, Obama) that we have to support the rebels....& we're still doing that! Its a crazy policy to support those who are not trustworthy, & are loyal to radical islam & hate anything western. There's just so much money to be made that it won't stop.
Additionally, each time we helped topple a dictator, someone worse comes in. Our leaders just don't want to learn from history. Arab spring turned into Arab nightmare, & there'll be more to come.
