The Nuclear Doomsday Clock is currently closer to midnight than at any point during the Cold War, the looming threat now is worse by that metric.

India and Pakistan both have nukes, and are currently engaged in 'kinetic' conflict.

The Russians have a good deal of nukes, of which a good % probably still actually work, and they have often threatened to use them in the ongoing conflict in/with Ukraine, which of course also involves many, just barely short of 'directly involved', nuclear armed NATO members.

Israel has nukes, they routinely and doctrinally threaten to use them against basically everyone (look up the Samson option / doctrine), prompting Iran to attempt to develop their own nukes, which now looks like they're closer to actually achieving thanks in large part to Trump horrendously mismanaging foreign policy.

North Korea has nukes, and they love to threaten Japan and South Korea with them.

China has nukes, and, as far as I am aware, are less belligerent in terms of specifically threatening to use nukes, they are quite belligerent in their claims of territorial sovereignty over Taiwan.

And now the US has gone full fascist, and we kinda have a good number of nukes as well, and our big, orange clown boy has threatened Canada, Mexico, Greenland, Panama, I forget how many others.

The recently proposed 'Golden Dome' is a callback to the SDI, 'Star Wars', which was never fully realized back in the 80s in part due to the fact that if this actually worked, it would destabilize the MAD, Mutually Assured Destruction, straregic paradigm... and could actually increase the chances of a nuclear escalation.

Well now I guess we are just commiting to that rhetoric at least.

The Boomers that grew up in the Cold War just convinced themselves they completely 100% won, problem solved, and devoted then their attention to hating the queers, setting up a domestic theocracy, inventing inssne conspiracy theories, getting scammed on Facebook, getting addicted to irrational rage porn media, and denying climate change and thus dooming the world to greater personal and economic precarity which will of course increase inter and intrastate tensions, making military and thus nuclear conflicts more likely.
