Economist Jeffrey Sachs has issued a stark warning over the escalating conflict involving Iran, the United States, and Israel, saying the world is heading toward a dangerous crisis. Speaking to NDTV, Sachs said Iran is unlikely to accept any ceasefire, citing a lack of trust after repeated strikes during ongoing negotiations. He criticised US President Donald Trump, calling his approach "confused" and warning that there are no internal checks within US and Israeli decision-making.
