US-Iran nuclear negotiations face a critical delay due to a scheduling dispute, amid growing tensions over uranium enrichment, sanctions, and looming IAEA censure.

With U.S. nuclear negotiations with Iran at an impasse, the danger of a military showdown between the countries has been growing in recent days. The signs are everywhere. It began with a report last week that critical drone defenses initially meant for Ukraine would be diverted to U.

President Donald Trump warned in a recent interview that he is "less confident" that the United States will reach a nuclear deal with Iran.

The US and Iran have been negotiating a nuclear deal for around two months, with Oman mediating. They have held five rounds of talks.

The United States and Israel are seeking to turn nuclear talks into a "strategic trap" for Iran, Iranian lawmakers said in a statement on Tuesday, days before a planned sixth round of Iran-U.S. nuclear talks.

Iran says intelligence documents taken from Israel better prepare it to respond to any potential Israeli air strikes.

President Donald Trump said Monday that new US-Iran talks this week could make clear if a nuclear deal is possible to avoid military action, as Tehran readies a counter-proposal on a potential agreement.

Russian President Vladimir Putin has offered to help resolve the nuclear dispute between Iran and the United States. According to the Kremlin spokesperson, Russia maintains close ties with Iran and Putin is ready to play a role in negotiations on Iran's nuclear program.
