On Face the Nation this morning Rubio claims ISIS is an immediate and significant threat to US national security and:
"targeting ISIS command and control in Syria"
"cutting off supply lines from Syria..."
"airstrikes in Syria and Iraq"
He also thinks we should protect Jordan at all costs, put more boots on the ground in Iraq (again? really?), and do more to support the "moderate anti-Assad rebels" in Syria.
I guess Iraq and Afghanistan weren't enough, he wants us in Syria and Jordan and to become Iran's proxy air force...
