He’s got some positions yet to change, but he’s obviously moving in the right direction.
Iran is a terror sponsor, and supplies weapons which are being used to kill our soldiers. The United States (possibly with help from UK and Israel) should bomb and destroy Iran’s oil & gas pipelines, refinery, oil and gas storage tanks, plus nuclear sites, and do it “yesterday”. Start with the easy ones and keep bombing for a couple of months. This would castrate Iran.
Bush could offer the Congressional Democrats a free ticket to Teheran before the bombing starts.
