Here comes trouble

Israel is talking about a full scale invasion of Lebanon. From the AP article:

But an Israeli army spokesman refused to rule out the possibility of a full-scale invasion. Israel broadcast warnings Wednesday into south Lebanon, telling civilians to leave the region — a possible prelude to a larger Israeli ground operation."There is a possibility — all our options are open. At the moment, it's a very limited, specific incursion but all options remain open[emphasis mine]," Capt. Jacob Dallal, an Israeli army spokesman, told The Associated Press on Wednesday.

This was tried first in 1978 and again in 1982; the latter leading to an eighteen year occupation of the south. If it had worked either time, they probably wouldn't need to do it again. The devil of the situation is that Israel doesn't really have any other options.
