Cote d'azur you have said
"US should have some leverage with Israel because without its political & military support (worth $ 3bn per year), Israel wouldn't last long nor would it also be able to give the proverbial finger to the international community re steadily increasing settlements into Palestinian territory. "
While it is true that Israel does receive that amount in military support, they have not received any economic support from the US since 2007. So if they can survive economically are you suggesting that it would be better they are wiped off the map by all Arab nations with their weapons as they have attempted to do in 1948, 1967, 1973, 1991 and so on? Or does "Israel wouldn't last long" have some other meaning?
In terms of steadlily increasing settlements into Palestinian territory, there have been settlement freezes and unfreezes over recent years but don't forget that in 2005 Israel uprooted entire communities of very hardline settlers in Gaza and removed them, handing back control of the entire area to the Palestinians. As a result of which the Palestinians started raining rockets on Southern Israel.
Not exactly a great response?
