Former President Barack Obama stated that the United States is now 'worse off' after a 15-week conflict with Iran, questioning the rationale and cost of the war. In an interview with NBC News, Obama expressed that despite significant expenditure and loss of life, the U.S. appears to be in a similar or worse position than before the war began. He also commented on a memorandum of understanding signed by Donald Trump with Iran, expressing hope for a lasting ceasefire. Obama reiterated his criticism of Trump's decision to withdraw from the 2015 Joint Comprehensive Plan of Action (JCPOA), arguing that the move prompted Iran to increase its nuclear capacity. The JCPOA had restricted Iran's nuclear program in exchange for sanctions relief. These remarks come as White House official JD Vance postponed a trip to Switzerland, intended to lead new talks with Iran concerning its nuclear program. Iran's chief negotiator, Mohammad Bagher Ghalibaf, emphasized respecting Tehran's 'red lines' in future talks. Separately, ExxonMobil executive Neil Chapman warned that oil prices could rise to $150-$160 per barrel if oil stocks hit critical levels.
