US launched Operation Epic Fury with Israel against Iran on Saturday, killing Iran's Supreme Leader Ayatollah Ali Khamenei and other leaders. Economist Kent Smetters said the conflict could cost the US up to $210 billion (₹19.3 lakh crore), with trade and energy disruptions adding $115 billion in losses. Reportedly, pre-war military build-up had already cost US taxpayers about $630 million.
