In the latest escalation of U.S. President Donald Trump's trade war, Washington has imposed new tariffs ranging from 25% to 30% on eight additional countries. Most striking, however, is a 50% tariff on Brazil, justified by what Trump called concerns over freedom of speech in South America's largest economy. This comes on the heels of a broader move targeting 14 countries—including major economies like Japan and South Korea—with steep tariffs unless trade agreements are reached by August 1. Trump also announced a 50% tariff on copper imports and a 200% duty on pharmaceuticals. What's driving this latest wave of trade threats? Can deals be struck before the August 1 deadline? And what might be the domestic and global consequences of targeting critical sectors?
