We pay a high price for supporting Israel unconditionally, including the fact that large chunks of the world will never believe anything we say about freedom/democracy/fairness/curtailing religious extremism because we never insist on any of those things in Palestinian/Israeli relations.

Voters are overwhelming willing to pay the price, don't want to do anything that lowers the price and aren't going to change anytime soon.

Whether it's fair, or should be changed, is a moot question because it isn't going to change.
