On the contrary. The real threat from Russia is already here. Sleeper agents with suitcase nukes. This has been the case since the late 7o's.
Of course, ours are over there too.
I think you misunderstand me. YES, they have the ability to build them...but they don't have the MONEY to, nor do they NEED it.
As that isn't the goal. This whole dog and pony show was for Trump's benefit. To force his administration to spend BILLIONS in updating our nuclear arsenal to combat these computer generated nightmares Putin showed to his people. It's actually quite brilliant.
It's a NEW way to fight the Cold War, get your enemy to spend, while you give the illusion of doing so.
Defenses not withstanding, there is also the concept of MAD (Mutually Assured Destruction) to consider. There's no winner here. So it is just saber rattling.
As for "invulnerability"...your words, not mine. We are indeed still quite vulnerable, but not from the fantasy Putin showed on screens. It isn't some silly nationalist pride, it's simple logistics. How many weapons, what type, what delivery mechanisms, from what global bases, etc.
Simply put, the US spends more than most other nations COMBINED on their military. It isn't just some "go US!" mentality, it's a simple matter of spending.
But even for ALL of that, even with weapons up there that we would think of as science fiction vs. actual existence....we are still quite vulnerable to good old subterfuge.
As for prepping, I'm as prepared as I can be for a US/Russia nuke exchange. If I'm at work, I'm vaporized. Simple as that. If at home, I've got a shot, depending on how many nukes (and what size) they send at our closest target.
A nuclear war is not as unsurvivable as folks may think. Don't believe me? Go look at some current pics of modern day Nagasaki for example. Go to nukemap.com Choose nukes actually still in service, and the detonation point of an air blast, over an actual legit target near you, and see if you'd survive.
