Besides the premise... once a nuke has been built, fielded and used... the onus has to be on it's deterrent value and not the destruction it causes... the genie is out of the bottle already.
And all you're doing is exposing yourself to it's consequences but not the reciprocal value it's endows the wielder. Which is why I strongly(dotards word) believe that a country with significant population and resources in a dog eat dog world ushered in by European colonial enterprises... as an instrument of destruction, not only of your civilization but to drain you off your resources!... should have nukes.
The US and zionist examples are the two still unfolding ones on the stage... both with impunity, sabotage, blackmail, non adherence to any conventions... nuclear or international law... impunity and recklessness, disregard for human life.
One must be really shielded or in a bubble to assume the bright side of real world consequences. Something that the west rewarded Iran in response to it's dithering... It cannot go without saying for the umpteenth time "THEY STARTED THIS WAR BY MURDERING THE ONE PERSON WHO STOPPED IRAN FROM GOING NUCLEAR!" make that make sense.
That you cannot make this judgement for your people ... unless you wish to become a victim of it... in this case Iran did. That puny little rats tail needs to be pounded till it mimics the pavement. Literally hundreds of thousands if not millions have paid the price for those who dithered on the very basic premise, safety of whom they were endowed to secure... it seems it is Baghdad all over for Muslims every few centuries... Mongols or mongrels! Just coming in and undoing those sleeping at the helm... the cushy life under the sun very easily becomes the new elixir, when devoid of any other... in hot burning sun of the desert and mirages all around.
So, back to the nuclear! Yes back to it and every thing out there in the toolkit for there just cannot be a repeat. Send polak packing!
