Trump has given some of his most hawkish administration officials, particularly his top diplomat, Mike Pompeo, carte blanche to squeeze and punish the Islamic Republic as aggressively as they wish in the coming weeks. All Trump asks is that they don’t risk “start[ing] World War III,” as the president has specifically put it in several private conversations with Pompeo and others, according to two senior administration officials.

That has left a host of options at the outgoing administration’s disposal—among them, a suffocating sanctions regime and a studied silence in the face of the assassination of Iranian nationals. Two officials who spoke to The Daily Beast said the administration is set to announce new sanctions on regime-linked companies and individuals in the coming weeks to solidify a years-long effort to paralyze Tehran’s economy.

Knowledgeable sources say those actions are designed to help fulfill various Trump officials’ long-brewing desire to make it more difficult for the Democratic president-elect to rekindle negotiations with Tehran and re-enter a nuclear deal. And it’s a scenario for which Biden lieutenants and allies have long prepared, having already factored into their Iran strategy that current U.S. officials would do nearly everything they could to undermine a revival of Obama-era relations between the adversarial nations.
