And for Israel, it will not take much to be provoked. The Israelis have been quite clear about their frustrations, after having been negotiated into a corner by the P5+1 world powers that ironed out the nuclear deal. Should Israel carry out a military strike on Iran under the shadow of the deal, the country would risk becoming a world pariah.
But Israel is under no such constraints with Hezbollah. In fact, Washington openly acknowledges the possibility of a conflagration between the two, and the White House is now openly touting the fact that it wishes to help arm the Israelis to handle Iran-sponsored regional aggression of this sort.
With the perception that its deterrence is shriveling amidst the very public spat with the Obama White House, Israel will almost certainly wish to make an example of Hezbollah. A victory against the strongest Iranian proxy in the region could make the kind of unequivocal statement Israel believes it needs while it waits to see if Iran holds up its end of the nuclear deal.
However, a war with Hezbollah would not be just another war in the Middle East. It could be the war to end all wars between these two bitter foes. The Israelis are not eager to settle for a partial victory or a bloody tie, as it has in the past. To establish deterrence in the age of an empowered Iran, Israel may seek total victory.
Hezbollah, for its part, will also not stand down. Armed with 100,000 rockets, a deadly arsenal of other ordnance, and now the deep pockets of Iran, it's hard to imagine a negotiated ceasefire.
