There is no way you are being serious now.
Hypothetical world is hypothetical.
The US has the military might to defeat any country. If you want to redefine what defeating a country means, then have at it. Generally though, the way the word defeat is used, would mean that my statement is correct.
If you take the military might of the US, and put it up against the military might of another country, the US would win. If you want to start giving hypothetical situations where its not military might vs military might, it stops being a question of military might inherently.
So, what is your actual claim, and what do you disagree about my initial claim?
Is this going to be round 2 of our previous discussion?
Also, what does this have to do with anything?
