Israel has had several decades of peace with Egypt and has received nearly $100 billion in U.S. aid since the Camp David accords. The original security guarantee came from U.N. troops stationed between the countries, and the Sinai being largely demilitarized, especially closer to Israel. The U.N. has since withdrawn, but (I think) the Sinai demilitarization is still in place.
The Sinai was never intended to be part of Israel. Israel did give up a military base and (IIRC) some oil wells in the Sinai.
I never heard of the Egyptian economy having problems that prevented further aggression.

My opinion about reasons why the U.S. is unlikely to attack or invade Iran:
2) Domestic pressure
3) World opinion / pressure
There supposedly was evidence that Iraq was attempting to get components for nukes before the invasion. I never understood why Saddam basically committed suicide instead of just inviting the inspectors back in.

Iraq remains in a state of hot war with Israel and could legally attack Israel at any time; that is unlikely only because of lack of military capability not lack of hostility.
Nobody on either side of the aisle realized the scope of the danger facing us.
The bad guys did a great job of catching us unawares, and there were low-level intelligence failures in detecting the flight-school hijackers.
