What's the Big Deal About the US and World Politics?

The US is the global heavyweight, so what happens in Washington matters as geopolitics is akin to a game of thrilling chess. At first glance, the influence is simple. The US is the world's most powerful country, like Rome during its prime, but today’s world is much more interconnected. The real kicker is technology. Weapons and military might have evolved, leaving us with nuclear war, a conflict so dire that no one can win—sound confusing? Let's back up. Envision a scenario where the US goes toe-to-toe with Russia or China. Any use of nuclear weapons would have devastating consequences and beyond that, a full-on nuclear exchange between big nuclear powers could even alter life on earth. The US isn’t just about nuclear weapons, either. It’s the most powerful country in NATO, the world's largest military alliance. Military bases are scattered across every inhabited continent. The dollar is the world’s reserve currency. It backs up the global economy, which is vital for international trade and finance. American diplomats play pivotal roles in negotiations around the world. This is because the US helps to mediate and resolve international disputes. The new Trump administration could bring significant changes worldwide. If the US reduces its role in NATO or completely exits, will Western Europe stay stable? Will Germany or Japan rearm? Will China react if East Asia feels the US wavering? The US shying away from climate actions might impact global warming.

A trade war could erupt if the US imposes significant tariffs. International trade has been crucial for the global economy. We saw in 2008 that a financial crisis could have turned into a depression. What happens to global prosperity if a trade war begins? If the US stops supporting the two-state solution for Israel and Palestine, what would happen if Israel's far-right government annexes the West Bank? Countries are already surveilling diseases and researching global health, but if the US leaves the WHO and other institutions, what happens to this global cooperation? The US has been the guardian of a critical international norm since WWII. It has led America to go to war against Iraq in 1991 and back Ukraine in 2022. But what if America tries to take Greenland from Denmark or the Panama Canal from Panama? Many people talk about China's rise, yet China remains firmly in second place. Despite China’s growth and the US’s relative decline, in absolute terms, the US is still ahead in military power, economy, demographics, political legitimacy, and diplomatic clout. The past few years have shown a relative decline, China becoming stronger as the US weakens. However, the US remains above China in almost every metric of global power. What happens in Washington is crucial, more so than in Beijing.
