To mitigate adverse consequences, Washington would need to take a number of steps before and after an Israeli strike, some of which might run counter to its instincts and preferences.
Although an Israeli military strike again Iran’s nuclear program is far from certain, the potential consequences for the United States are clear. Such a development would present major crisis-management challenges — and, perhaps, opportunities to advance U.S. interests.
The immediate challenge would be to limit escalation by constraining Tehran’s freedom to act, minimizing the damage caused by its retaliation, and keeping Hizballah and other Iranian proxies out of the fray. Moreover, by curbing Iran’s escalatory options in the Persian Gulf, Washington might prevent a prolonged spike in oil prices. This could in turn help preserve international support for efforts to prevent Tehran from acquiring nuclear weapons.

Struck me as interesting that he portrays Hezbollah as more independent from Iran than we normally do.
