When I read articles like this, I have to wonder: Either these people are complete lunatics or arms dealer lobbyists.
Why did countries develop their nuclear arsenals again, ensuring mutual destruction in case of war? So that we now stockpile stupid amounts of ammunition for imaginary wars between powers that can destroy humanity for good if such a war ever happened? We should again sacrifice millions for what? There'll be nothing left worth defending.
So no. I will never prepare am mindset for war. It's the utmost idiocy.
