Each time Israel attacks Gaza and massacres its trapped civilian population ? at the end of 2008, in the fall of 2012, and now again this past month ? the same process repeats itself in both U.S. media and government circles: the U.S. government feeds Israel the weapons it uses and steadfastly defends its aggression both publicly and at the U.N.; the U.S. Congress unanimously enacts one resolution after the next to support and enable Israel; and then American media figures pretend that the Israeli attack has nothing to do with their country, that it's just some sort of unfortunately intractable, distant conflict between two equally intransigent foreign parties in response to which all decent Americans helplessly throw up their hands as though they bear no responsibility.
