I’m gonna answer from the perspective of someone who believes the world is a better place when it is led by America without reverting to a thin jingoist ideology. These aren’t my views, but a steel man of someone I would disagree with.

Why does America feel the need to control the world?

In the wake of the world wars, we realized that the world is best off with one power to lead the world. No powers and multiple powers will result in another world war. We were the best position to take that role after WW2 and resist the Soviet union’s attempt to gaining that position.

Do what they say?

Many of these countries don’t do what America says because America says it. Heck, many go against what we say. But they believe in a better world and when they remember that, they undtand that America is putting themselves in the most danger by clearing that path for the rest of the free world.

Instead of taking care of their own problems at home?

The problems we have at home are pretty limited. Most of these problems are born out of laziness. But we keep the criminals in check both at home and abroad.

When did the US become police officer of the world and enforcer?

If we didn’t step up after ww2, the world would have slipped into another world war or deem communism run rampant.

I guess my question is who gave the Americans the right?

The civilized world at the end of WW2. And under our leadership, the world is safer and healthier for it.

I say this as an American. But would not the world be a better place if we just minded our own business and quit nation building and stoking non existant fires?

From communism to extreme religious views, we are the only ones who are capable and willing to step up and protect the world against that. It’s a difficult and thankless job.
