If we don't initiate nuclear war, a nuclear war would be on Putin. He can do that with or without us defending Ukraine, I don't see how you could blame nuclear war on anyone but the aggressor. Put this pathetic dog down.
It's completely irrelevant on who would be the nuclear war. A nuclear war will wipe out an absolutely humongous part of humanity. Even if you survive, you will be doing much much worse as essentially all supply chains will get broken.
You are missing the point which is: your greatest fear will be turned and used against you by your enemy. So the only actual solution is to stand up and confront what you fear. Then you have a fighting chance to avoid that fate.
But, fine, let's play this game. The US is sends troops into the Ukraine. You do understand this is right at Russia's border. What does Putin do? He'll engage. Great, now we're in a shooting war with our nuclear rival. Now do you want to roll the dice this doesn't escalate further. Does Putin go after neighboring NATO countries? Now the US has to escalate further to defend an ally. And if the US/NATO pushes into Russia, does Russia go nuclear?
This is why the Cold War stayed COLD. We didn't directly engage Russia on anything close to their borders. Yes, we fought two proxy wars in Asia and just look how that turned out.
Do you really want to roll the dice and hope your neighborhood isn't a parking lot in the next five years?
We are dealing with "insane" people. If he is willing to use nukes over Ukraine, I can guarantee he does not plan just taking Ukraine. When should we react? Ukraine, Romania, Poland, Austria, Germany?
He says no. Probably enjoying one last sunset outside before closing the hatch! I can't help but wonder about our h n founders, safe in their bunkers in NZ, reading dog eared copies of The Soveiregn Individual. And then I wonder about all the Ukraine war news stories leading up to this being and flagged and burried here. I hope it's just coincidence. As I have said before, they think they can survive nuclear winter, no problem. But those assumptions are built on test of single small bombs. 10,000 going off at once is an order of magnitude worse, and might easily produce surprising effects. Science is always finding surprises in old experiments when they crank the power way up.
And I am no HN founder, but I live in Eastern Europe. NATO planes and helicopters kept flying overhead all day and my house doesn’t even have a basement.
So I bet we are closer to the danger than you are. And I also bet that the ones doing the flagging and burying are other brave "class warriors" and "eaters of the rich" who can’t accept that their beloved ideology has created monsters like Putin while the capitalism they despise has given the world prosperity, (relative) peace and Elon Musk (the last one's a mixed blessing, I admit).
PG if you are reading this, I love you really, man. And if there's any room left down there for a resourceful fella, I will work for bunk and board. (In fact, I've been stockpiling tins since Feb 20, so I only need the bunk ;)
If Putin directly attacks the West you'll get your dream. Until then you might actually stop advocating nuclear Armageddon. If you are really willing to do this you are no better.
