I see this playing out this summer as first Hamas launches a massive missle attack. As The IDF responds than Hezzbollah chimes in, then Syria. Syria will hunker down and wait for Isreal to come to them, planning on reprising Olmert's dithering from last July.
This scenario will either have Isreal on the defensive fighting 3 fronts, or the politicians get out of the IDF's way and Lebanon, Syria, and the West Bank/Gaza get creamed. Scenario 2 will be were Iran comes in. If Iran comes in we will cream them but lose the Middle East oil for quite a while.
The only certainty is that the mussies always, always overestimate their abilities and believe their own BS.
