U.S. President Donald Trump has told his aides he is willing to conclude the American military campaign against Iran even if the Strait of Hormuz remains closed, according to a Wall Street Journal report citing U.S. officials. The report notes that such a move could prolong Tehran’s control over the vital waterway and complicate future efforts to reopen it.

Officials said Trump and his team recently reviewed the situation and believe that forcing the strait open could extend the conflict beyond the president’s preferred four-to-six-week timeframe. The president’s main objective, according to the report, is to destroy Iran’s naval and missile stockpiles, then de-escalate the conflict while applying diplomatic pressure on Tehran to allow free trade.

Washington may also press its European and Gulf allies to take the lead in reopening the strait if necessary. Although military options remain available, Trump is reportedly not prioritizing them at this stage.
