All establishment media, thinktanks and both parties are pro US imperialism in general which necessitates wars of aggression, you have to read this critique more like it's taking place within the pro-war group. Like everybody is agreeing with the Iran war in principle thats not even up to debate anywhere in the mainstream. It wouldn't even occur to most Americans that "no wars at all" is even an option to begin with. To most, their "freedom" and safety depends on wars thousands of miles away.
One example you can look for (it's everywhere) is in the way Chinese military capabilities are discussed by media like that, what is often brought up against them is "the lack of experience", without a hint of irony alongside the implicit view of china as the dangerous aggressor and rival. Imperialism is just the air they breathe, they don't notice it at all. Peaceful coexistence is not an option.
