Could Russia succeed in a Missile hit of the US

Over the years I've read military strategy that insists it would billions to one for a foreign power to actually be able to hit US soil in real time. The missile or whatever would be destroyed before it hit.

But is that really true? Those of you who know, what do you think?

Are any other boomers 60 plus being triggered back to the sixties with this stuff?

I think the whole Iron Curtain scare must have affected me as a child. I started having flashbacks to those TV reports we used to see on the news in the 1960s. My anxiety is through the roof. I'm pacing and raging.
