U.S. President Donald Trump has raised the idea of American forces seizing Iran’s Kharg Island, its main oil terminal in the Persian Gulf.

“Maybe we take Kharg Island, maybe we don’t. We have a lot of options,” Trump told the Financial Times in an interview Monday. “It would also mean we had to be there (on Kharg Island) for a while.”

Iran has threatened to mine the Persian Gulf if its territory is invaded. The United States and Israel kept up their attacks Monday on the Islamic Republic, even as there were signs of progress in nascent ceasefire talks.

Trump also said that Iran had agreed to allow 20 ships carrying oil through the Strait of Hormuz starting Monday morning and continuing over the next few days “out of a sign of respect.”

“I would only say that we’re doing extremely well in that negotiation but you never know with Iran because we negotiate with them and then we always have to blow them up,” he said.

The war has already threatened global supplies of oil and natural gas, sparked fertilizer shortages and disrupted air travel. Iran’s grip on the strategic Strait of Hormuz has shaken markets and prices.

Iranian lawmaker suggests Tehran leave Nuclear Nonproliferation Treaty

The comment by Alaeddin Boroujerdi to Iranian state television comes after hard-liners in Tehran long have suggested taking the step.

“Why should we accept the restrictions?” Boroujerdi said. “We are not seeking a nuclear weapon anyway. But it’s not like that we are supposed to observe the rules of the game and they bomb us.”

The Nuclear Nonproliferation Treaty is a landmark international accord meant to stop the spread of nuclear arms. Countries that signed it agreed not to build or obtain nuclear weapons and allow the International Atomic Energy Agency to conduct inspections to verify they correctly declared their programs. Iran has been restricting IAEA inspections for years and hasn’t let them visit the three enrichment sites bombed by the U.S. in June.
