This is a red herring. Rogue regimes will, by construction, seek the security offered by nuclear weapons. Hence the need, where possible, to apply diplomatic or military means to prevent exactly that.

The US is the rogue regime in this scenario.

That’s counter to what happened for several decades when we actually cared about preventing it. Few regimes at all sought them and several were convinced to abandon nuclear programs.

Even democratic regimes should start acquiring nuclear weapons - ie. every EU country, given Trump's comments and stance about the EU.

Not easy though, the US has to basically allow it.

Did the US allow all the other nuclear countries to develop nuclear weapons? There are quite a few states that could easily and quickly develop their own nuclear deterrent and the US is in a much worse position now to deter them from that.

Tell that to Iran.

The current administration WANTS Europe to develop the military necessary to defend themselves so we don’t have to pay for it. We’ll probably send them the schematics if they haven’t already infiltrated whatever servers we keep them on.

What if France 'donated' some nukes to every EU country (okay, maybe not Hungary) ?

It won't happen, but I wonder what could the US possibly do about it.

Nothing. We could and would do nothing. If we wanted to do something, it would be sanctions. We’re not so far gone as to invade Europe.

The problem is they’d have to donate delivery systems too and I believe the only part of the triad they have is submarines.

Most European countries simply couldn’t use it. But some could.

Every sovereign nation should do. The notion that uppercase D "Democracy" is the only valid type of sovereign state is uppercase L liberalism propaganda.

I wish more people understood this.

The worst part is the people who make these decisions understand it and they do it anyway because the proliferation will occur in someone else’s term.

North Korea, Israel, and Pakistan prove you wrong.
