I did specify "any conventional military force"; 'winning' an occupation/insurgency is quite another matter, particularly when the 'win conditions' are political rather than military. And doubly true when those political win conditions are poorly defined in the first place.

But trust me, defense industry lobbyists are very eager for the US Government to spend even more money to address these shortcomings...

The ability for the U.S. to wage numerous simultaneous wars is about the cold war. It's effectively the basis for NATO's deterrent effect, reducing the number and scale of wars in Europe and Asia compared to the pre-NATO era.

Most of Ukraine is not “destroyed”. In fact most of it has not even been attacked.

Well, then the same is true for Afganistan. By destroy, I did not mean they have attacked every village.

So, what do you mean?

I am in Ukraine and I do not feel like I am in a destroyed country.

> the US managed to destroy the country

That’s a downright lie.

Define "win"?
