I would again flag my utter lack of comprehension of the apparent obsession with US warhead numbers (ultimately does the difference of just over 1,500 to just under 1,600 actually materially impact the US deterrent?) shown by some contributors.
That's because some of us have done the math.
First, how many nukes successfully delivered to the target *and* properly detonated do you need to have to serve as a proper deterrent? Back in the USSR days, I'm sure the Pentagon assumed that they'd need to nuke several hundred Soviet targets... and the Soviets knew that. So, do you need several hundred nukes? No, you need several *thousand.*
Pulling numbers directly out of the same dark hole that Bernie Sanders pulls his economic projections from, let's do some armwavy math. Let's say the US has 1,000 ICBM-deliverable nukes, and Da Enemy has 250 targets that would need to be destroyed. Great! You can destroy them twice, and stir the ashes twice again!
Well, lessee. Start with 1000.
Let's say the enemy first strike takes out 25% of the ICBMs. You now have 750 nukes.
Let's say when you give the order, 95% of the surviving launch crews hit the button. You have 712 nukes.
10% of the ICBMs fail to launch. Down to 640.
10% of the ICBMs fail in flight. Down to 576.
10% of the warheads are mis-targeted. Down to 518
25% of the warheads are taken out by anti-missile systems. Down to 388 warheads.
10% of the warheads fail to survive re-entry. Down to 349.
10% of the warheads fail to detonate. Down to 314.
10% of the targets were more hardened, or more mobile, than expected and survive. Down to 282.
Hmm. Looks like you've just *barely* got enough to get the job done once. But wait! Of the initial 1000 warheads, 25% were laid up for maintenance in the first place (because they were made thirty years ago from materials with a twenty-year shelf life), and were never getting off the ground. So you really only deliver 211 nukes. Da Enemy survives, and since they not only stockpiled more than you did, and you're a smaller nation with fewer targets, and their nukes are more modern and less buggy... they successfully nuke all *your* targets three times. Then they wait a few weeks to see who pops out of what holes, then nuke *them.* And they *still* have enough of a stockpile of nukes and delivery system to tell the rest of the world to shut the hell up and toe the new line.
You have an arsenal of a whole lot of nukes for the same reason you give snipers more than one bullet.
