Why do you think Israel has survived all these years ? It is ONLY due to the fear that it has instilled in its hostile neighbors about what the repercussions of attacking Israel could be. And it has to keep up the fear perception by making sure that any kind of violence against it, is dealt with a firm (sometimes disproportionately so) hand.
Israel survived because its parent states Britain and US have supported it throughout and given it more ammunition than a state its own size should ever need. Why is that? It has been free of official scrutiny because its parent nation US is a veto holding power at the UN, and just so happens that US is also the sole superpower. So any resolutions that should be put into action later by UN, are killed off w/out being passed by US. Fair Playing Field? that's a ha ha moment.
To make things more interesting US has vested interests and vice versa in all the neighboring nations that could possibly take a stand against Israel, so US does all it can to appease and please the "fitted" rulers that run those nations just so Israel can continue with its daily slaughter of innocent Palestinians without those nations coming to the rescue of Palestine. Give Palestine the same technology as Israel and let them EARN their right to a nation, if that's the way it's going to be eventually. Why give one side extreme firepower and the other mere stones and rocks to throw? Fear? You tell me...
