Only the most extreme right wingers defended Israel when they invaded Gaza in 2008, dumping chemical weapons on two hospitals among many other egregious crimes. Only the extremists are ready to defend the execution of people on the aid flotillas. One American was shot in the back of the head execution style. Normally you expect America to defend it's own citizens from these type of things, but extremist right wingers cheer on the foreign government in this case. Watch Obama below espouse the litany of extremist right wing positions on these issues, and also watch Finkelstein's commentary, which is very interesting in exposing Obama's cynicism.
As Finkelstein points out, at least conservatives believe what they say. With Obama it seems he's a right wing extremist when that's where the money is, and who knows what he might say tomorrow if the money shifts.
