It is Clinton's fault for saying we should take out secular dictators and hope that democracy will flower (it didn't in any nation but Egypt, which elected Muslim fundamentalists after which the military had a coup). Chaos in Libya, Yemen, and several other nations.
Then Clinton created the Syrian crisis by attacking Assad, ignoring Russia's HUGE naval base there that they would protect. So Russia came to Assad's aid. What does Clinton do? She arms anyone willing to fight Assad, not caring what they did with the weapons. The groups that became ISIS took our weapons to create a Muslim theocratic state out of parts of Syria AND Iraq, and she didn't care because hey, they were fighting Assad.
And Obama has kept up arming "rebels", not caring that they murdered innocents, set up sex slave markets and are worse than the Afghanistan Taliban.
