Why would Israel worry about who is leaving Lebanon by ship when the border to Syria is wide open? As for checking who leaves, fine, but let people leave after checking. That is not what is happening.
As for destroying Lebanon to "isolate" Hizbollah, I don't think that argument flies either. Israel is punishing all of Lebanon for being weak-kneed. Let's admit that. Why don't they turn their firepower on Damascus and Tehran, where the real problem lies. Hizbollah is a "messenger boy." Killing the messenger won't change anything. You have to cut off the head of the snake, wouldn't you agree?
Jay Leno says the US government has stated it's not easy to move 25,000 across the border in Lebanon.
...so we should hire the Mexican government to do it for us.
I see your point, but could Israel take on Iran which would have the backing of the entire ME?
I do agree.
To add to the above, actually I think both are necessary. Isolate the hezzies and blast Teheran.
