If you think we ‘happened’ to keep a large standing army just because we were defending Europe.

The plain fact is we didn’t even try and reap the peace dividends following the Cold War. We doubled down and found an excuse to pad the pockets of the MIC.

If we’d shrunk down instead of maintaining all this obsolete gear, it’d be easier to be proactive to changes in warfare like drones. We wouldn’t maintain fleets of fourth gen fighters and build out our fifth gen fleets.

You maintain military production capacity by having a strong civil industrial capability.

As we learned in WW2, it doesn’t take much to convert from making cars to making tanks.

Bonus side effect: prevents us from getting embroiled in nation building or getting after commercial wet dreams for regime change when it takes 2-3 years to build up a force.
