Maybe the Israeli are not planning a full scale ground invasion until they notified U.S to allow time to plan for departure of Americans.
Evacuation is going to be dicey if Hez and its sisters have free run in Beirut and around.

I doubt a ground invasion will happen, and if it does it won't be any time soon. Something like this takes a lot of time to plan, and I doubt that Israel was expecting to take this action. Plus they are very weary of Hezbollah which had years to prepare for an Israeli invasion.
