"Then the administration tied it in to the regional dispute between Israel and its enemies, as if that's about international terrorism. No, it's not"

This quote by Chris Matthews is describing the Bush administration's attempt to connect the Iraq War to the local conflict between Israel and its opponents. Matthews is slamming the administration for trying to make this connection, as he believes it is not associated with worldwide terrorism. He is implying that the Bush administration was utilizing the local conflict between Israel and its opponents as a method to justify the Iraq War, although it had nothing to do with worldwide terrorism. Matthews is recommending that the Bush administration was using this regional dispute as a method to control popular opinion and gain assistance for the war. He is likewise suggesting that the Bush administration was not being truthful about the reasons for the war, and was rather utilizing the regional dispute as a method to get public assistance.
