*I am in no way thoroughly informed on the whole situation with Israel/Palestine, so my opinions reflect this limited knowledge.

What I've read recently about the situation in Israel and their relations with Palestine leaves me wondering why the U.S. seems to 'blindly' back Israel.

An unquestionable majority of the U.N. voted in the first steps towards full recognition of a Palestinian state, with the U.S. in the minority (not a 50% minority, not a 25% minority, not even a 10% minority, but rather a less than 5% minority.)

  In the most recent Gaza Strip struggles, Israel bombed Palestinian news headquarters with the intent of disabling antennae used for "terrorist activities"...i.e. broadcasting news? Unfortunately this evil, terrorist weapon of mass destruction (news antenna) was also shared and used by British Sky News, so when they heartlessly bombed the building, in a Nazi-esque maneuver to stymie opposition media, they killed non-palestinian reporters....oops.
  They bombed Gaza's Association for Disabled Athletes, an arena and rehabilitation center for Gaza's less handicapped persons. (Taking for granted the expectation that Israel has 'top-of-the-line' missile tech, thanks to their faithful backers, the U.S., could this really have been an accident?)

 Today, it has been reported that Israel is now beginning building on key disputed territory, effectively saying "Screw-You U.N. you're not the boss of me, we will do whatever we want!" To paint a better picture for you what building on this land means; Palestine was granted the first steps toward globally recognized statehood, so Israel still having 'effective' control over the land starts plopping down buildings.

What I see in Israel, is a group of people who want to remove themselves from an Israeli state and be granted independence. Do you really blame them? Israel is basically a military state, forcing everyone of their citizens to serve in the military (off course there are exemptions).

I guess I just don't understand.
