The U.S. will likely need to instantiate its support of Israel. By punishing terror infrastructure, resulting the loss of dozens of U.S. lives, Iran and its Hezbollah proxy would be deterred from sparking a broader regional war. 6/6

Yes, a lot of power projection. But Iran and their proxies will test what happens when they step over the line. The promise of a bark is to bite when needed. Von Clausewitz as usual a good guide.
