A friend writes:
"If Israel is on the cusp of preempting Iran, it would be a very smart thing to crush Iran's surrogates on the border and neutralize prepositioned weapons that might be brought to bear when the gloves come off with the Farsi folks. At least, this is what I would do in advance of an attack on Iran. Tick-tock, tick-tock.
Another friend suggested that if this analysis is correct, then southern Lebanon will be next.
