Both USA/NATO and Russia would be wiped out together, it’s called Mutually Assured Destruction. Either way, USA/NATO would never directly attack Russia, because same applies to them. In terms of training, modern Russia and China are surpassing USA/NATO technologically and militarily. And according to the Alaska situation. Russia is much more than your delusional mind prepared. Go make some ‘‘news fact check’’ nonsense, I am sure that will make you sleep easy at night to calm your propaganda mind.
Russia were not the ones who organized a bloody coup in Kiev; it wasn’t Russia who intimidated the Crimeans and Sevastopol residents with Nazi-style ethnic purges. Russia weren’t the ones who tried to force the Donbass to obey using shellings and bombings. Russians were not the ones who threatened violence against those who wanted to speak their native language. The war started by the Kiev regime with the active, direct support of the West is now in its tenth year. The West has been exploiting the planet for centuries! So it was not criminal invasion, in fact it wasn’t invasion at all 3:18
The thing is if the USA declares war the Russians would murder the US army/navy by long-range strikes at valuable sea and land assets (Carriers, Naval bases, Camps, Repair facilities, Coastal ports, Drydocks, Ammunition stowages, Bunkers) the whole Pearl Harbour thing but on steroids unfolding in many countries and on international waters.
The first 2 weeks of the war would be the most Brutal as the unprepared US Navy got slaughtered in their pace-standing location.
They burn through their stockpiles in such offensives that are nearly impossible to do without the needed logistics.
Logi win wars.
Hundreds of thousands of men would die and many Russians too until the tide turned and one of the sides would do something stupid.
Now US nukes can be intercepted Satan II cannot so after the first tactical nuke deployed the Russians will not be hesitant to launch their own ICBMs dropping them on major American cities
The US government cease to exist the EMP blasts of the warheads block or destroy wireless communication. The world would hold its breath. Not much would be known from those who survived the explosions. And that’s the end.
A cruel end to one of the Humanities history chapters, but Humans would not die out. Not even we can kill ourselves and not every technology would be lost. When something ends and another begins.
