Why is Israel bombing the barracks of the Lebanese Army if its the Lebanese Army they want on the border?

Why are they bombing Christian sea ports if they're after Hezbollah?

Why are they targetting areas outside traditional Shiite areas?

Why does Israel think they can accomplish anything by indiscriminate killing?

Looks to me as if Israel is attacking Lebanon rather than seeking out Hezbollah. Seems to me that Israel wants a full scale war.
