Beware becoming the barber
Because all you see is haircuts
If I go to a barber, he'll tell me I need a haircut.
If I go to a retired Army special forces guy, he'll tell me the US won the Cold War due to Irregular Warfare. (Specifically, "the [United States]…destroyed the USSR through hostile actions below the level of direct large-scale armed conflict, i.e., through [Irregular Warfare]."
Strategic assessment is part of the strategist’s toolkit. And sometimes that toolkit is obviously broken or off or underperforming. This quotation above is one of those cases.
For now, to keep a lid on the worm-can—let’s set aside the debate over the merits of this gentlemen’s argument. Some will undoubtedly be partial to his view, and others will oppose. Whether or not the US felled the USSR due solely or mostly through means that can be described as "irregular warfare" is almost beside the point. It's the one-term-answers-all approach that's disturbing. The full-throated certainty of the bumper sticker argument.
