Make no mistake, I have lots of critical things to say about the US. The war on terror was a stupid reaction on the rise of terrorism and extremism, for example. But the US has in general been a real good force for the world.
Wait till you learn what might makes right really means, you will soon regret armchair snarks.
Read up on what the German army did in Belgium in WW1, or occupied France & Eastern Europe in WW2. What Japan did in China. What King Leopold did in the Congo, or what the Russian army is currently doing in Ukraine.
There were atrocities committed by the US in the Middle East, yes, but nowhere near the level of barbarism in the conflicts mentioned above, and typically not conducted as a matter of official policy.
