I don't know what country my opponent will choose, so I'm just going to present some statistics for the United States. We can argue about them in the next round.
The United States is the world's largest economy by nominal Gross Domestic Product. The annual GDP for 2019 is estimated to be $21.3 trillion, which means America has a higher GDP than any other country on Earth. About 60% of all funds used in global trade are in U.S. Dollars. In many countries, the dollar is either the official currency or the de-facto currency, which gives the United States a lot of power over the economies of those countries .
The United States also houses many of the world's largest companies, such as JPMorgan Chase, Bank of America, Apple, Wells Fargo, Amazon, Microsoft, and countless others . These companies posess a lot of influence internationally and thus make the United States even more powerful.
The United States is widely considered to have the most powerful military in the world. As of 2018, the United States annual defense budget was $587 billion, which means it spends more on defense than any other country in the world. The United States spends more money on its military than China, Russia, India, France, the United Kingdom, Japan, Turkey, Germany, and Egypt combined .
The United States has 1.35 million active personnel and an additional 0.8 million in its seven reserve components. The United States Department of Defense is the largest employer in the world, meaning it hires more people than any other corporation or government agency. Roughly 120 million Americans, or about 30% of the population, are fit for military service. Overall, the United States has the third largest military in the world by personnel .
The United States has the largest air force in the world, with 13,762 aircraft. The United States also has the largest navy in the world, with a staggering total of 415 ships. Out of those 415 ships, 19 are aircraft carriers, meaning the U.S. has the most aircraft carriers in the world . The United States has an inventory of 6,450 nuclear warheads. Only Russia has more nukes than the US, and the difference between the two countries is just forty nuclear weapons .
The United States is a member of NATO, meaning that it has 28 other allies which will defend America if it is attacked. NATO is the largest military alliance in the world, and it consists of other powerful countries like Great Britain, France, Germany, Italy, and many others. If someone tries to attack the U.S., they won't stand a chance as nobody is strong enough to fight with all of NATO .
