Of course no country will directly aid the Palestinians as long as the US backs Israel. I do feel sorry for both sides of the conflict. For the Palestinians because it's hopeless for them and for Israel for the day when the US is no longer willing or able to back them. So many problems could be solved if they found a peaceful resolution.
Now I know you're saying "that just wikipedia" but maybe read the cites. Or do a google search. Educate your self. You might find that the US government has done far worse in acting out foreign policy goals... And publicly acknowledged it: http://en.wikipedia.org/wiki/CIA_sponsored_regime_change. Almost as bad as the Brits.
But I understand your need to deny anything that the US does that could be construed as bad since this might force you to take personal responsibility for your own life.
