Background and Context

The United States has deployed stealth bombers over the Pacific Ocean, fueling speculation about potential military action against Iran. This development comes as President Donald Trump considers joining an Israeli offensive against Iran.

Who are the Key Players?

The US bombers in question are the B-2 Spirit, a long-range, low-observable (stealth) strategic bomber capable of carrying the heaviest payloads for the United States, including the GBU-57 Massive Ordnance Penetrator (MOP)—a 13,607 kg bunker-busting bomb designed to penetrate 61 meters of soil before detonating.

Why is this Relevant?

The GBU-57 MOP is the only known weapon capable of destroying deeply buried Iranian nuclear facilities. While it is unclear if Israel possesses this bomb, its potential use highlights the seriousness of the situation.

Recent Developments

On Saturday night, multiple B-2 bombers took off from a central US base and were subsequently tracked flying near California’s coast, accompanied by refueling aircraft, according to The New York Times and aviation tracking websites.

Government Response

When contacted for comment, the Pentagon referred inquiries to the White House, which did not respond immediately.

Trump’s Schedule

President Trump, who seldom spends weekends in Washington, is expected to return to the White House on Saturday night for an unspecified “National Security Meeting.”

Trump’s Ultimatum

On Friday, Trump stated that Iran had a “maximum” of two weeks to avoid potential US airstrikes, suggesting he might make a decision before the two-week deadline he announced the previous day.
