The Soviet Union lost the Cold War because the US tricked the military-intelligence dominated Brezhnev[0] "administration" into diverting too much investment towards defense. The result was under-investment in infrastructure and agriculture that doomed the USSR over the long run. The US was able to sustain this because it had a larger industrial base.

Shall we foolishly end up on the other side of that?

Do you really think there's a chance the US would suffer from food lines and other shortages due to over-investment in defense a la the Soviet Union?
