U.S. President Donald Trump has warned Iran to reach an agreement with the United States within 10 to 15 days or face a potential military strike. Speaking at the inauguration of a peace board in Washington, D.C., on Thursday, Trump said that last June’s joint U.S.-Israeli attack on Iran had paved the way for a ceasefire in Gaza. He claimed that without U.S. action against Iran’s nuclear facilities, peace in the Middle East would have been difficult to achieve.

In response, Iran issued a counter-threat through its permanent representative to the United Nations, who wrote to Secretary-General António Guterres stating that any attack on Iran would trigger retaliatory strikes on all U.S. bases and infrastructure in the Middle East. The envoy emphasized that Iran does not seek war but would respond if attacked, holding the United States responsible for any consequences.

According to a Wall Street Journal report cited on Friday, the United States is considering an initial limited strike targeting Iranian government buildings and security infrastructure to pressure Tehran into a nuclear deal. If Iran refuses, a broader campaign could aim to topple Ayatollah Ali Khamenei’s government.
