U.S. officials believe Israel has narrowed its targets for retaliating against Iran’s missile attack, which officials say will likely focus on Iranian military and energy infrastructure. Israeli officials have yet to finalize decisions regarding when and how they will respond, and there is no indication they will target nuclear facilities or carry out assassinations. The U.S. has prepared to defend regional assets from Iranian counterattacks, but it is unlikely to provide direct military support. Officials continue urging Israel to focus on military targets and avoid escalating the conflict further.
