President Donald Trump has imposed a 25% tariff on goods from countries engaging in business with Iran, intensifying pressure on Tehran during widespread protests. This move, announced via social media, affects major economies like India, Turkey, and China. The tariffs, justified under the International Emergency Economic Powers Act of 1977, remain in effect pending a Supreme Court ruling expected in early January.

Trump views these tariffs as a tool to fix the nation's fiscal issues and exert pressure on foreign governments. Regardless of the Supreme Court's decision, tariffs will remain central to his economic strategy, aiming to revive U.S. manufacturing. The list of affected countries and sectors is extensive, with tariffs ranging from 10% to 48% on various goods, including steel, aluminum, and pharmaceuticals.

The impact is global, with countries like China, the EU, and Vietnam facing substantial trade disruptions. For instance, China, the most affected, sees a 24% tariff on goods worth $272.7 billion. The EU faces a 13.5% tariff on $284.8 billion worth of trade, while Vietnam and Japan are also significantly impacted.

These measures are part of a broader strategy to leverage trade as a political tool, reflecting Trump's populist economic platform.
