The diplomatic fallout would be huge. Signatories to the Nuclear Non-Proliferation Treaty and members of NATO trying to stop another member of NATO from becoming a nuclear-armed state, especially if that came with Russian assistance. which Turkey has form for using. Also,take into account Sultan Erdogan's apparent ambition - https://www.arrse.co.uk/community/t...that-turkey-cant-have-nuclear-weapons.295059/
Yeah, agree, but the issue is as the US/Europe push Turkey further and further away, the Turks have less to lose, and of course the US/Europe too.
Can the US/NATO do without Turkish bases and restricted access to the Black Sea? Probably, but it will be a pain. Turkish forces, by their sheer size, contribute much to NATO at a staffing and troop level. Important when the rest of NATO forces (including ours) seems to be getting smaller and smaller.
As will losing excellent basing facilities on the doorstep of the Mid East and Iran. Turkey getting nukes and becoming a Russian ally.
Of course it's a price we in the west can pay, but we have to decide is it worth it? I am still unsure what the Turks have done that is unacceptable to us that some other NATO countries or US allies have not done. Maybe I am ignorant here.
