I don't believe there'll be a war, at least not in the foreseeable future, Russia in 2025 isn't Germany in 1939.
They can't even defeat little, under armed, with not much of an air force, Ukraine & the Russian people don't want to fight one.
Russia cannot even take Ukraine's energy infrastructure, despite having built it in Soviet times.
Yes we do need to up our game and should have done so years ago, certainly after 2014 but a European war? who with? the losses Russia has suffered in the last 3 years is phenomenal, both in equipment and lives.
I hope i'm not wrong.....
