Persuasive argument against the nuclear warfare

That only 250 warhead are needed to put the earth in nuclear winter
A Tsar Bomba (nuke with highest yield of 100,000 megatons developed by the Russians)in Tokyo results in 12 million dead instantly and a further 5 million in slow death.
Only the supergiants (US,Soviet Union,China,India,Uk,France,Pakistan,Israel and North K) have nukes with a fewer number of countries in the nuclear triad “hub”(US,Soviets,China,India) therefore these posses an unfair disadvantage.
Avearage nuke yield is 100 megatons which can wipe out a whole country.

They are not effective as one would use them unless they want to watch WW3 from their TV.

They produce high amount of radiation when you make them
Once produced they take a long time to dismantle.

I know everything about nukes so don’t hesitate to ask me about the topic:)
