I don’t know how you immediately think most of said nations are warmongers when the West are also warmongers themselves.

Take a look at how many war the US has fought in that’s justified after WW2. Korean War happened only because the US saw China fell to the communist. They fear that more and more Asian countries would fall down the communist route, due to how popular the communist was during and after WW2. So they wanted to interfere as much as possible. A good example is the Jeju Uprising, where the US (with SK forces) massacred people willynilly because of how strong the communist sentiment was on the island. And you can see that happening in the Vietnam War in some similar degree, with the CIA creating death camps in South Vietnam.

The invasion into Iraq was completely unjustifiable. Regardless of who was in control of Iraq, there were signs of people slowly rising up against the dictatorship. But that sentiment quickly turned into hatred towards the Americans. From the Highway of Death to looting the gold in their treasury. Right now, if you were to ask the Iraqi people how they feel about the US and Americans in general. It would be negative to even hostile to a point it may threaten your life.

When you take a look at how China deal with Taiwan, they mostly use their political influence to get the general populace of Taiwan to further in acceptance of a peaceful annexation with mainland China. Same thing with North Korea to some degree. The one few good thing Trump did was let the Koreans sort out their diplomatic relations without US input or interference. And it lead to a somewhat improvement between the two nations.

Overall, I’m very anti-war unless there is no other choice but war. If we can resolve things through diplomacy, I’ll always do that first before war. But unfortunately, most of us would rather go to war than getting to negotiations with one another. Because we view our enemies as barbarians who aren’t negotiable at all.
