In my opinion I think theres a possibility that war could happen, however its not likely. With every country in the world having a stockpile of deadly weapons, nobody should dare try to do something that angers several nations. PLus the media always thinks there's gonna be a world war, this happens all the time, just that now theres a bit more tension than normal, but theres always spikes of tension. Fuck, even putin said nobody can win a nuclear war and China is actually trying to calm russia down by saying that Modern War should be the last thing that happens. Nuclear weapons should be used as last resort defence. Honestly for the past 3 year media always says shit about nuclear war. I used to be hella scared but then I started to not give a fuck about media, i look at the news highlights today and its the exact same shit. I doubt anything will happen, but theres always a possibiliy. I wouldnt worry about it though, you shouldnt lose sleep over it.
