I agree with you, straffo.
Before the land of the palestines was stolen, the arab nations were quite positive or at least neutral to the USA. (In fact most of them didnt knew that there was something like the USA
)
Because of the history they mistrust the old colonial powers - like France or UK or Turkey - but they had no reason to hate the USA.
After WW2 the mad decision to construct Israel brought them to side with the USSR and so they became part of the cold war.
Its normal, that a country ignore crimes done by one of his own
allies.
Even today the USA is ignoring many of the terroristic acts of the
terroristic government of Israel - although some of the crimes have the "quality" of the Nazi massacres of WW2.
But its also normal, that the palestines and the arabs are not ignoring the fact that the USA - the so called fighter of world-wide-terrorism - is supporting (Israeli) terrorism.
This is a sad example how hate could be fueled to the madness we have all seen in September 2001.
