Big mistake thinking like that. Tell that all the big empires that died. Nukes are a must. There is no "to big to fail/die" never was and never will.
I'm not saying what should happen. I'm saying what will happen. Turkey won't go for nukes before Iran reaches missile quality nukes. I don't have any idea on a possible Turkish program. Also don't know if there are guarantees by others or anything. Just that if need be they will spend %10 of GDP in a year to get them, any way possible. We don't do preventative maintenance lol.Too long of a timeframe, we should be working on it NOW.
Perhaps we should, since deterrence in the space of chemical and biological weapons doesn't work like nuclear deterrence.
Nuclear explosions are infinitely more flashy(ha!) events, with everyone knowing who packs what, its more likely a party that uses nukes won't be able to dodge the consequences.
But a competent biological attack is near-untraceable. Thus exponentially increasing the chances of an attack.
In short: M.A.D doctrine is incompatible with chemical and biological weapons. You either have them or you WILL get rekt by them.
Turkey also won't go for biological or chemical weapons. I also don't agree on the deterrence provided by such weapons being important. All users of it either also have nukes or are failed states, for a reason.
