Iran threatens retaliation against nations joining US 'economic war'

The standoff between Washington and Tehran has entered a new and more volatile phase. On Saturday, Iran's top security official issued an unmistakable warning: any nation that joins the United States in imposing economic sanctions will be treated as an enemy and face retaliation. Mohsen Rezaei, secretary of Iran's Supreme National Security Council, laid out the calculus plainly. Iran would first attempt diplomacy, he said, urging countries to distance themselves from American pressure. But if they refused, Iran would strike—targeting their interests directly. He called the threatened response "seismic."

The warning arrived as the Trump administration prepared to announce what it has called the "most crushing economic operation" yet against Iran. Treasury Secretary Scott Bessent amplified the message with a stark formulation: "You're either with us or against us." He specifically called on China, which purchases more than 80 percent of Iran's exported oil, to abandon its trade relationship with Tehran. Bessent is scheduled to unveil the details of the new sanctions package on Monday.

This escalation reflects a conflict that has been grinding on for nearly six months, since late February when the United States and Israel launched joint military strikes on Iranian targets. That operation prompted Iran to close the Strait of Hormuz, one of the world's most critical shipping lanes, effectively halting traffic through the waterway. The blockade sent prices for oil, fertilizer, and other commodities surging globally. On Saturday, Iran announced it would permit some Iraqi oil tankers to pass through, a modest gesture that underscores how tightly it controls the chokepoint.

Yet even this limited opening masks deeper dysfunction. According to reporting from the region, the situation in the strait "remains vague." Iran has made clear it will keep the waterway closed until the United States lifts its own naval blockade on Iranian shipping. Talks between Iran and Oman about managing traffic through the strait are ongoing, but no agreement has been reached. The diplomatic machinery, in other words, is still grinding without producing results.

Egypt has positioned itself as a mediator, with its foreign minister speaking by phone with his Iranian counterpart on Saturday. The two discussed efforts to "create an environment conducive to de-escalation" and explored the possibility of returning to diplomatic channels—both the ongoing Omani-mediated talks and a potential revival of the US-Iran memorandum that once governed their nuclear relationship. The Iranian foreign minister, Abbas Araghchi, also spoke with Pakistan's army chief about strengthening peace and stability in the region.

But these diplomatic overtures stand in sharp contrast to the hardening rhetoric from Washington and the explicit threats now emanating from Tehran. Iran's Foreign Ministry spokesperson rejected the incoming sanctions as an illegal assertion of "extraterritorial sovereignty," arguing they violate international law. The United States, for its part, is threatening economic consequences not just for Iran but for any nation that provides it "any type of lifeline." This pressure campaign is designed to isolate Iran completely—to cut off its oil sales, its access to international finance, its ability to trade.

What makes this moment particularly precarious is that the two sides appear to be moving in opposite directions. The Trump administration is tightening the economic noose. Iran is warning that it will respond not with further negotiation but with direct action against countries that comply. Egypt and other regional actors are calling for a return to the diplomatic table. Yet the fundamental conditions for serious negotiation—a pause in escalation, a willingness to compromise, a shared sense that the current path leads nowhere good—seem increasingly absent. The Strait of Hormuz remains closed. Commodity prices remain elevated. And the threat of further retaliation hangs over any nation considering alignment with American sanctions policy.
