Russia is a nuclear power, there were even a couple articles like a year or 2 ago talking about how Putler was, at least trying to, remove any safeguards between his button push and the actual nukes.
Thus preventing another occurrence of when that Russian missile operator received orders to fire nukes because radar said there was in inbound missiles but the operator decided to ignore them and it turned out to be a glitch or whatever.
Yes and no, America does have a similar sized arsenal, but the difference is the president isn't in control of the button itself. The "nuclear football" is more like a private key and order transmittal device, basically if the nuke missile silos receive an order from it, they can trust it's legit because the presidents football signed it. The silos firing mechanisms are also all independent. They can still choose to not insert their key and turn it (of which it takes 2)
In Russia, it may very well be that Putler has actual control of the actual button that controls the actual firing mechanisms of the silos themselves.
