Nukes - A case of dammed if you keep them, dammed if you get rid rid of them.
Option 1 - We get rid of them, saves loads of money, everyone happy for a few years. Another "regime" far from our shores, decides to build them with the associated delivery system and then "drops hints" on what they want us to do. Hmmm, we then moan saying we should not have got rid of them.
Option 2 - We keep them but have cheaper mini nukes and can't be "asked" to do things
In my time i.e. Cold War vintage, the phrase MAD ( Mutually Assured Destruction ) was used and it worked i.e. nuke us, we nuke you, no one wins.
By all means get rid of the nukes and save a fortune but please do not moan in the future when a foreign power becomes a big bully with their nukes and force us to do what we know is wrong but can not do anything about it.
The nuke genie is out of the bottle and it can't be put back in. Even certain foreign nations who hate the West are not that dumb to lob a few nukes around, hmmm well possibly not.
Think back to GW1 - America rushed the Patriot out to Israel to shoot down skuds as Israel would have converted Baghdad to a large parking lot if one of those skuds had contained chemicals etc when it hit Tel Aviv.
No easy solution, dammed if you keep them, dammed if you get rid of them.
