US Energy Secretary Chris Wright said a nuclear agreement with Iran may not materialize, suggesting Washington could continue military efforts to dismantle Tehran’s ability to develop and deliver nuclear weapons. In a Sunday appearance on ABC News’ "This Week," Wright said the campaign could extend into future administrations and described it as part of a 47-year effort involving regional allies. He said the U.S. military’s primary objective was to halt Iran’s crude exports and impose economic costs. Iran’s parliament speaker, Mohammad Bagher Ghalibaf, warned of more severe responses after U.S. strikes on Iranian oil tankers, while CENTCOM commander Admiral Brad Cooper said the U.S. would continue protecting its forces and pressuring Iran. President Donald Trump said the U.S. has "total control" over the Strait of Hormuz, but shipping data showed commercial traffic through the oil chokepoint had fallen by 50%. The conflict continues to threaten energy markets, while earlier diplomatic efforts mediated by Pakistan and Qatar remain disputed by Washington and Tehran.
