I don’t recall Libya or Syria ‘harboring terrorists’ at the time of their overthrow/attempted overthrow. If ‘harboring’ be the criteria, then why have we not gone after Iran or the Saudis who have been harboring the Wahhabis or Pakistan??? Are their terrorists’ different? And no, I don’t like policies that create a mess, that we don’t clean up, that then come back and bite us in the ass. Do you??
Syria, along with Iran is on our list of state sponsors of terrorism. And every we chance we get we should kill ISIS members, Qud members and all the members of the other alphabet soup jihadists groups. Sorry to break that line of thought.
