Next time it won’t be as pretty as the 1940s.
Let’s be serious - Germany is in no position militarily or psychologically to carry out a war.
If tomorrow they got attacked by Switzerland and with no one aiding them, the Germans would lose and be conquered.
If the USA declared non-nuclear war on Germany and no one else intervened on either side, I’d expect the war to be over in hours, not even days.
Germany’s military is underfunded and disrespected due to WWII.
What she’s talking about is an economic fight.
