Every action has a reaction - definitely! But don't forget that his applies to Israel as well as the Palestinians. Israeli arrogance has led them to believe that this law no longer applies to them or, in other words, that they can do whatever they want without incurring any realistic opposition. You clearly think that will always be the case. I don't. One way or another (and let us hope that it is through peaceful means) I believe that the Palestinians will eventually get a viable state and with E. Jerusalem as its capital. Israel's only real ally is the US (Europe follows along half-heartedly) but the US is a bankrupt state that is gradually losing its super-power status and ability to control events beyond its borders.
