Why is the United States so bellicose?

In the past two years, I have witnessed the Russo-Ukrainian War, and now Israel is entering Gaza, with the shadow behind it being the United States. It inevitably makes people curious about the role of the United States. We need to ask a fundamental question: Why is the United States so fond of war? Why does it welcome war? In short, why is the United States so bellicose?" Former U.S. President Carter, in a letter he sent to President Trump during his term, wrote the following: 'Do you know about China's punitive war against Vietnam since 1979, the war between mainland China and Vietnam? After 1979, has China engaged in any wars with other countries? Not a single one,' Carter said. 'We, on the other hand, have consistently been in a state of war. In the 242 years since the founding of the United States, only 16 years have been peaceful. Just think about what kind of country this is.' According to former President Carter, the United States is the most war-prone country in the history of humanity. Carter mainly discussed the wars in Iraq and Afghanistan. He mentioned that we spent three trillion dollars on military expenses for these two wars, while mainland China did not spend a penny on war, which is why they have been able to develop to the extent they have today. This is his advice to Trump. To be honest, Trump also had a challenging time. After World War II, during Trump's four years in office, the United States did not engage in any wars. He is the only president in the past four decades during whose tenure the United States did not experience war.
