Iran intensified its public threats against Israel and the United States on Sunday, erecting a large and ominous sign in central Tehran that openly signals hostility as preparations continue for another round of negotiations between Tehran and Washington.

The display, placed in Falastine Square in the center of the Iranian capital, features the phrase “Rain of Missiles” alongside a map depicting central Israel. The message is being viewed as an unmistakable and deliberate threat aimed at Israel, delivered in full public view at a sensitive diplomatic moment.

Against that backdrop, Iran’s Foreign Minister Abbas Araghchi made clear earlier in the day that Tehran has no intention of abandoning its nuclear ambitions, regardless of the consequences.

Araghchi said Iran is willing to consider certain constraints on its nuclear activities but will categorically reject Washington’s demand for a full suspension of uranium enrichment.

“We insist on our right to a nuclear program, even if it leads to war,” he said in a conversation with diplomats in Tehran. “They attacked our nuclear facilities but did not achieve their goal. The only option left for them is negotiations.”

He further framed Iran’s posture as ideological defiance rather than purely military power, adding: “The secret of the Islamic Republic’s strength lies in its ability to say ‘no’ to the great powers. Our atomic bomb is the power to say ‘no’ – not physically, but ideologically.”

U.S. negotiators, meanwhile, are pressing for sweeping concessions, including a complete end to uranium enrichment, severe restrictions on Iran’s ballistic missile program — with one proposal calling for a maximum missile range of 500 kilometers, while Israel is demanding a stricter cap of 300 kilometers — and a halt to Tehran’s support for allied armed groups throughout the region. Those groups include Hezbollah in Lebanon, Shiite militias operating in Iraq, and the Houthis in Yemen.
