re: Why Israel is targeting Lebanese infrastructure.
Doesn't justify, in my mind, attacking civilians loading fruit trucks. Better ground-truth is required in this war amidst the civilians of Lebanon.
In my view, only a ground force can tackle Hizbollah, and there is some question whether Israel is prepared to engage in the numbers and for the time required to winkle-out the guerrilas.
And then there's the "hearts and minds" aspect, which has been a political disaster so far..
There's no easy answer here. Things will probably get worse before they even seem to get better.
