I'm saying that a civilization that tried to be galactduck by exterminating other civilizations to take their resources would run into similar problems as the Soviet Union and the United States have. It is extremely inefficient and belief in the falsehood of it all eventually kills you off.

The U.S. as a group did not profit from war. A few parasites did. To truly progress as a society, you eliminate the parasites.
Sorry to be annoying about it. When people start spreading the rumor that Weyland-Yutani is right, that centralized aggressive power actually works, my fallacy radar goes off like bonkers. Because parasites will destroy you eventually if you don't get rid of them, you won't get to rule the galaxy.
