Consider this, without US obstruction Israel would have been forced to not have settlements where they invade lands they agreed to give to Palestine. If they were forced to not have settlements then the opposition would have no other reason to continue hostilities.
Now I am no fool. Palestine is not the reason that there is so much fighting, antisemitism is the reason for the violence. However if settlements weren't an issue then it would be a cake walk to get the world to condemn the rest for being antisemites.
Yet with America standing in the breech of any of that so we can test bed our weapons and ostensibly have a foothold of democracy in the middle east.
Still if you remember the election BOTH our candidates were bending over backwards to see who could both suck and swallow the Jewish lobby at the same time.
