Every time we have toppled a secular dictator, whether it was Iraq, Libya, Syria, Egypt, chaos has ensued and radical Islam has become more of a threat. The Senate has just voted to give the Obama administration the authority it needs to train and arm members of the Syrian opposition. But not before certain Senators voiced some very strong objections. Sending arms to so-called moderate Islamic rebels in Syria is a fool's errand and will only make ISIS stronger. So with the additional steps I ordered last month, we're speeding up training of ISIL forces, including volunteers from Sunni tribes. I warned that these arms might end up in the hands of jihadists and that one day we might be forced to go back to fight against our own weapons. Within a year that prediction came true. ISIS rides around in a billion dollars worth of U.S. Humvees. We must protect and defend the Constitution against all enemies, foreign and domestic.
