I think perhaps, you misconstrue what Mr. Barnet is trying to say.

I don't see him as saying we need a military for national defense. What we do have is a military designed, built, and functioning as a force engaged in global hegemony.

"We live in a country that has warred aggressively against fictitious enemies, meaning without cause or necessity, more than any other country on earth. It is stated, and supported, that the United States has been at war for at least 93% of its entire existence. I firmly believe this number to be much higher, and with proper consideration, it is likely closer to 100%. If one is to determine the actual damage done, the actual harm due to direct war, proxy war, what is insanely considered ‘collateral damage,’ what is the horrid long term cost to human life in the aftermath of this terror, the total number of causalities, including the dead, would be tens if not hundreds of millions of innocent people. But what is sold to the wrongly named ‘public, is that this country is and has been the savior of ‘democracy,’ a completely evil and failed ideology, which is a gross lie beyond the imagination of any sane and thinking human being."
