The U.S. military conducted fresh strikes on Iranian targets in retaliation for an attack Saturday morning on a commercial tanker, as President Trump threatened the possibility of restarting the war.

Why it matters: The second wave of U.S. strikes in Iran over the last 24 hours comes amid increasing tensions in the strait —and could put the shaky U.S.-Iran memorandum of understanding at risk.

The latest: Iran responded to the U.S. strikes with drone and missile attacks on Kuwait and Bahrain, according to the Kuwaiti army and Bahrain’s interior ministry.

Driving the news: Earlier Saturday the Iranian Revolutionary Guards Corps launched an attack drone at the M/T Kiku tanker, which was passing in the Strait of Hormuz with more than two million barrels of crude oil, CENTCOM said.

• The incident happened several hours after the U.S. conducted strikes on Iranian targets in retaliation for another attack on a commercial ship on Thursday.
• The Iranians retaliated to the first wave of U.S. strikes by attacking targets in Bahrain early Saturday, in addition to the tanker strike.

State of play: CENTCOM said in a statement that U.S. aircraft targeted Iranian military surveillance infrastructure, communication systems, air defense sites, drone storage facilities, and minelayer capabilities.

What they’re saying: Trump, in a Truth Social post Saturday night, confirmed the strikes and threatened more.

• “There may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job that we very successfully started,” he wrote.
• “If that happens, the Islamic Republic of Iran will no longer exist!”

Flashback: It was just 10 days ago that the U.S. and Iran signed the deal to end the war and start diplomatic talks.

• The next day, Trump told “The Axios Show” that the deal represented an “unconditional surrender” by the Iranians.
• Tensions have steadily ramped since then, though.
