I agree. Personally, I think the buildup should have been listed as censored information for the press. Let Hezbollah find out about it when they are engaged.
In theory- you're right. But I think part of the problem is the visibility of this- there are spies everywhere on both sides- and the added complication of media with cameras everywhere.
At the same time..it wouldn't be surprising to learn later there were spec ops going on..things we can't see taking place.
