Israel will cease offensive operations after that. If it reaches the River, she will hold the high ground and Hezbollah can do squat to return. And Israel will hold the area til a new international comes in. But until Sunday night, I think - Israel is going to go for broke. You'll see the army try to achieve its maximum lines before the ceasefire takes hold. Note Olmert did not say it will take effect immediately. He's leaving his options open. It depends on how Hezbollah plays its card. Let's remember who was begging for a ceasefire and Hezbollah is crushed to learn the Israelis will keep shooting for two full days!
