Nukes prevent any war from happening between any powerful nation.
If we spent 1 tenth the amount on our military, we'd still have the power to blow up the entire world X times over.
I just think that if you have the ability to destroy the entire world, then that's a powerful enough military and you don't need anything more for defense.
The only thing preventing Eastern Europe from being invaded is the conventional military. The US will never risk it's own existence for another country. The Russians know this.
So no, I don't believe that the US would do that and I am happy about that.
The US would only use Nukes if there was an attack on the US.
I want the US to stay out of all wars that aren't directed related to attacks on US soil and US citizens.
If the EU is worried about invasion, then they should have their own military to defend themselves.
The reason it's impossible to win a war against the current US military is because the US has spent an obscene amount of money building it for decades.
If the US military were not capable of defending Eastern Europe, Ukraine, Poland and the Baltics would be under Russian rule today.
