From what I have seen of the various Arab Israeli wars, over the last 50 years, the Pan Arabic States start the process off by overt or covert agitation/acts of war, Israel overcomes their massed armies, takes lots of their land, and eventually yields some of it back upon the urging of the UN. Israel rearms herself with help from the US, the Pan Arabic States rearm with the help of Russia/USSR, and the process starts all over again.

Well, guess what, Russia isn't near as eager or able to help rearm the various militant Arabs, because she has spent herself out of money trying to keep up with the US militarily and in space. This leaves our Arabic brethren only Iraq and Iran, two states far enough away that they generally don't get involved in these wars unless they do something extremely dumb, in which case Israel doles out hurtin' to them too. Build a Breeder Nuclear Reactor, guess what? Israel bombs it down to glowing rocks, sand, and muddy water.

Start encroaching on what Israel considers her buffer zones by launching rockets or suicide bombers across a common border, Israel reduces the buildings from which the missiles or suicide bombers were launched, and closes down her border so the various neighbors can't come to work in Israel, and let them eat sand for a bit.

Israel only needs the help from the US to rapidly rearm them in aircraft and missiles, and given time they can even build these for themselves. I certainly don't hear of any of the neighboring Arabic states producing anything on their own except trouble, and border incidents. Most of their Arms and equipment came from Russia, or the USSR, who may well decide not to rearm these folks as their money doesn't spend much better than the Russian Ruble. The Arabic states that have a source of money, usually in oil, are not directly involved in invading Israel, although they may support militant groups involved in trying to overthrow the Israelis. They know that they can't reliably ship oil unless some form of peace reigns, so it is to their advantage to attempt to restore some from of peace in that region, although this does not keep some of these states from aiding the terrorist groups.
