President Donald Trump said on Friday he would bomb Iran again "without a question" if intelligence were to find that Iran can enrich uranium to a level higher than what he is comfortable with. "Without a question. Absolutely," he told reporters in the White House briefing room.

The U.S. Department of Homeland Security warned Americans of a "heightened threat environment" on June 22 that could include attacks on U.S. soil. That fear appeared to dissipate when Iran attacked a United States military base in Qatar June 23, injuring no one.
