Why do Americans fight everywhere?

Maintain hegemony. After World War II, the United States was called the most powerful country in the world and became the police of the world, so it was the overlord. For the United States, waging war is to safeguard its hegemony. Reflect the strength of the United States.

Transfer contradictions. For the United States, it is actually a very loose country, because it is a patchwork immigrant country. All regions, ethnic groups and ethnic groups are very divided.

Plunder the world. As we all know, the United States is the financial center and military center of the world. Moreover, the American economy and strong foundation are that the dollar plunders the world and weapons deter the world.
