It will be like that Monty Python sketch where the cop says "Halt!! Or I will say 'halt' again." The Israelis could line Palestinian civilians up against walls and machine gun them and the US would make no meaningful response whatsoever. Sickening.
Nice to see that the Europeans at least take this a little more seriously, though as long as the US stands uncritically behind the Israelis the Brits and French will probably be told to go pound sand.
