Probably not until we fight another war to win it. Since WW2 that has not happened. And that is not to denigrate those that fought or served anywhere any time. It is unfortunate that we lost so many good men and women in wars our leaders were not committed to winning decisively and violently.
I doubt if we will ever go to another WORLD WAR. Our battles seem to be totally regional--for some reasons usually trivial.
The world is too different now. With the Army-invented Internet there is instantaneous communication. Once there is communication, there is USUALLY some form of understanding. Once we understand each other, we tend to NOT fight with each other. Doncha think?
Also, our leaders are different: we reap the rewards of the 60's assholes flower children running the world.
We called Governor Gerry Brown "General Moonbeam." SUCH a loser.
Oh well, life in this world is a blink of an eye. Better to prepare for the afterworld...ETERNITY. Yikes.
