Is it me or does that seem like an awful lot of troops to comb northern Gaza for rocket-launching and Hamas infrastructure?
If I was the suspicious type, I'd wonder if the Gaza operation was just securing the Israeli flank before plunging into Lebanon to hammer Hezbollah while that group is committed to Syria fighting for Assad.
UPDATE: Strategypage says that Israel has mobilized 60,000 (I assume all services) to fight the 1.6 (or so) million Gazans.
But rather than being prepared to take on Hezbollah, Strategypage's Dunnigan and Bay said (in Strategy Talk) they suspect Israel is going in heavy to Gaza to really damage Hamas.
