“The best shot at knocking out the most fortified part of Iran’s nuclear program comes down to a giant U.S. bomb that has never been used in war,” the Wall Street Journal reports.

“The GBU-57—also called the Massive Ordnance Penetrator—is a 30,000-pound behemoth encased in a high-density steel alloy designed to plummet through 200 feet of mountain rock before exploding.”

“Military analysts said the large bunker buster has the best chance of getting through to targets like the Fordow uranium-enrichment facility, which Iran buried under a mountain. Its existence has driven speculation that the U.S. could get involved in Israel’s attack.”

Washington Post: Trump debates bombing Iran in pivotal moment for presidency.

“The U.K. is very well protected. You know why? Because I like them. That’s their ultimate protection.”

— President Trump, quoted by CNBC, explaining that Britain would be protected from future tariffs.

“Iran has prepared missiles and other military equipment for strikes on U.S. bases in the Middle East should the United States join Israel’s war against the country,“ the New York Times reports.

“The United States has sent about three dozen refueling aircraft to Europe that could be used to assist fighter jets protecting American bases or that would be used to extend the range of bombers involved in any possible strike on Iranian nuclear facilities.”

Wall Street Journal: “Trump is considering a range of options, including a potential U.S. strike against Iran, as he meets with top advisers in the Situation Room on Tuesday.”

President Trump dismissed March testimony from his director of national intelligence, Tulsi Gabbard, who told Congress that the intelligence community believes Iran is not building a nuclear weapon, Politico reports.

Said Trump: “I don’t care what she said. I think they were very close to having it.”
