According to Schwartz, at any given time, the US has four to five nuclear-armed submarines "on hard alert, in their patrol areas, awaiting orders for launch." Even high-ranking officials in the US military don't know where the silent submarines are, and there's no way Russia could chase them all down before they fired back, which Schwartz said could be done in as little as five to 15 minutes.
But even a strike on a relatively sparsely populated area could lead to death and destruction across the US, depending on how the wind blew. That's because of fallout.
The US has strategically positioned the bulk of its nuclear forces, which double as nuclear targets, far from population centers. But if you happen to live next to an ICBM silo, fear not.
There's a "0.0 percent chance" that Russia could hope to survive an act of nuclear aggression against the US, according to Schwartz.
So while we all live under a nuclear "sword of Damocles," Schwartz said, people in big cities like New York and Los Angeles most likely shouldn't worry about being struck by a nuclear weapon.
