if things carry on the way they are then yes, probably.
I really doubt it will be nuclear war though. Or world war as people imagine it when they think of world war.
But things will get worse, will get more tense, we will not be able to ridicule the very idea that we may not be completely safe in our little democratic bubble.
Russia and china will probably team up a bit more. the enemy of my enemy is my friend and all that. Im not sure what if anything north Korea would or could do but who knows? He's crazy enough to do anything.
War in the west in this day and age is unlikely to be all bombs and hand to hand combat. When it comes to attacking the west at least, bombs would be part destruction part willy waving. cyber attacks can bring a country to its knees far faster and more completely than bombs.
tbh if we'd just open our eyes we'd realise the world is already at war and has been for some time. It's just that people still think of ww1 and ww2 when they think of war. It doesn't have to look like that for it to be war. also for some people if it isn't affecting them then it isn't happening.
I honestly don't think we'll have conscription or nuclear bombs or anything like that. War will look different but if people think war cannot happen or in some ways isn't happening already, they're fools.
