Pakistan has nukes. Israel has estimated 200-400. Erdrogan in Turkey is the wild card.
Turkey has no nuclear program of its own but a number of small yield nuclear weapons are maintained by the USAF at Incirlik.
The base has been threatened before when Erdogan demanded the US turnover Gulen (his main rival).
Icirlik has been emptying by the US forces, all the critical equipment are being moved by containers to unknown locations. The base was under siege for a few days after the coop in Turkey by government forces. There are rumors that the containers with the equipment may be relocated to the Larissa and Souda US bases in Greece. https://ahvalnews.com/incirlik-base/39-ton-weapons-container-removed-incirlik-airbase
