As an American, the US participation in the Ukrainian conflict as well as the Palestinian genocide are beyond reproach. Many describe them as proxy wars, but I'm not there yet.
During the Cold War, there was the Afghanistan, Vietnam, South America, Cuba, etc. These were proxy wars because there was a clear adversary on the other side. The Soviet Union.
Now, who is that? Russia? China? Who is "our enemy"? I see it was war is good for business and projection of power.
