Billt, you are precisely correct. If the surrounding mooslum countries were to lay down their arms today, there would be peace in the Middle East tomorrow. If Israel were to lay down its arms today, there would be no Israel tomorrow.
The seemingly easy overthrow of these various despots has more to do with simple human rights than anything political. If you squash any group of people under the boot of tyranny for long enough, that group will eventually realize they have nothing more to lose and rise up. The uprising is facilitated if all classes are squashed--then they tend to unify, at least for the period of time needed for the overthrow.
Mubarak realized that the entire diversity of Egyptian citizens had finally had enough. (This may have been the only time in history that the Coptics and the Shia and the Sunnis were all in agreement.) He further realized that his military was not going to fire upon its own citizens. He left in 18 days. It was a smart move on the part of Mubarak.
Gaddhafi (at this moment) retains control of the military, and they have shown no compunction about shooting their citizens. It may be a little harder to topple this one. Eventually, he will go as do all despotic regimes. But remember, it took generations for the Russians to overthrow the Tzars and generations more to overthrow the reds who assumed power. The North Koreans have yet to rise up. It's not something that happens overnight--especially if the despot is deemed to be benevolent. But it always happens eventually.
I think the troubling thing about what we are seeing in the Middle-East is that the Mooslum Brotherhood appears to be the only well-established and wide spread group in the area. They appear to be positioned to assume a leadership role, and they hate the West.
I believe we are just beginning to see how truly ugly things can get.
