I had misread one of Jeff Head's comments and made a reply that shouldn't have been there...outside of that one line (or two), though, the rest of my post was valid...
...i.e. Syria and Iran won't let Hezbollah and Hamas suck them into Al Qaeda's plan for a wider war...and if they did, then it's curtains for Tehran/Damascus.
And if they don't, Hamas and Hezbollah still get taken out by Israel in the meantime.
