More of a question of when than if. And I have a seaking suspicsion that the US military will join the long list of imperial armies that were unbeatable…until they were beaten.
When Iraq (whom we helped) tried to inavde Iran their government sent wave after wave of unarmed children into Iraqui fortications until they were overwhemled.
The U.S. will beat itself, just as Rome and just about every other imperialist nation has.
