Paul criticizes Clinton’s foreign policy in a Wall Street Journal op-ed, saying that interventionism led to the rise of ISIS:
To interventionists like former Secretary of State Hillary Clinton, we would caution that arming the Islamic rebels in Syria created a haven for the Islamic State. We are lucky Mrs. Clinton didn’t get her way and the Obama administration did not bring about regime change in Syria. That new regime might well be ISIS.
[…] Those who say we should have done more to arm the Syrian rebel groups have it backward. This is not to say the U.S. should ally with Assad. But we should recognize how regime change in Syria could have helped and emboldened the Islamic State, and recognize that those now calling for war against ISIS are still calling for arms to factions allied with ISIS in the Syrian civil war.
