Donald Trump’s announcement of a universal 10% tariff on all imports into the USA, beginning on 5 April, has sparked global alarm. An additional wave of steepened tariffs on approximately sixty nations, including China and EU countries, begins on 9 April. Trump claims the move will revive American manufacturing, calling it overdue payback for unfair trade practices. However, international leaders warn the tariffs will spark economic turmoil and a potential global trade war. Ursula von der Leyen called it a ‘major blow’, while China, facing a 54% total tariff on some goods, promised ‘resolute countermeasures’. Allies like the UK and Australia have urged restraint, while others, such as Brazil and Canada, plan reciprocal actions. Japan, Taiwan, and South Korea also condemned the move. Trump’s tariffs have rattled long-standing allies, confused diplomatic partners, and raised fears of escalating economic isolation. Critics argue that US consumers may bear the burden, with higher prices and increased global instability looming. For an opinion about what a huge gamble Trump is taking, see
