I suppose world peace is defined as tyrants and terrorists running the world and US doing nothing about it? US has used military action to promote long term peace and stability. China actively harasses sovereign nations in the pacific region and may invade them some day.

Both of you are right. China is a bully and so too is the United States.

Superpowers bully.

So the question is about how to handle this situation between conflicting interests. We need to figure out how to keep as much peace as we can with two superpowers, and make them both agree to something they feel great about.

These aren't facts but this is how I feel:

With the opportunity to lift all of humanity from poverty around the globe in our lifetimes, and opportunities to use technology to solve physical mysteries, and with global economic trade both can prosper from I hope, I wish, I imagine that there are ways to find a symbiosis.

I'm afraid of hawks playing a game that forces there to be other hawks - of there being a race to the bottom into a cold war (whose balance and controls have been loosening - the US is not without blame here).

How do you feel about it?

The instability that we currently have in the world is in almost all cases caused by actions of the US. Afghanistan, Iraq, Iran, Saudi Arabia financed terrorism, the list goes on and on.

Whenever the US intervenes it's either creating a mess or involving itself in a mess that was created by the US in the first place.

The stability and victories of peace are also due to the US. It is the US world order. It has problems, but it's also very difficult to determine what alternate histories would look like.

Neither the US nor China are evil or good. They are both rationally inclined to their own interests, which compete. Each have their own issues and histories. The US for the most part tries to find solutions that meet ideals and at the same time meet US interests.

The ideas you talk about are great and noble, but the implementation shitty. Iraq is no better off than 10 years ago. In Syria, first Assad was the enemy, so they helped the militias, who turned out to be Isis. I'm not saying that China will always remain peaceful (internationally), but so far, their non-invasion policies have resulted in much less deaths than the US's invasion policies.

By "guaranteeing stability" you mean disband the dictatorships and armer groups they established in order to stop the CPPP expansion? Now, these same leaders that militarized the world in order to stop the Soviet Union are deciding our domestic laws in order to stop another country from threatening their economic and military supremacy.
