ELI5:What's the point of the U.N. if the U.S. is going to lead every conflict/humanitarian aid/war?

I don't understand why the US gets involved as much as it does when the UNITED NATIONS exists.

Because the UN and it's resolutions are largely toothless.  It's an international body with no real authority to make anyone do anything.

People/Countries will follow along though after someone takes up leadership.  So the US as the premiere military and economic power in the world assumes this role.
