There are no US nuclear missiles in Turkiye.
There are nuclear gravity bombs -- the B61 -- stored at Incirlik AB near Adana (and at other facilities in Europe).
The B61 is strictly deployed from aircraft, not rockets or missiles.
"The B61-12 is the only remaining US tactical nuclear weapon, with 200 stockpiled, approximately 100 in the US, and another 100 in certain European NATO member states under its nuclear sharing arrangement, maintained by munitions squadrons."
Israel, with its 7.2m Jewish population, is ranked 15th militarily out of 145 countries in the world by the Global Firepower Index (GFI); Iran is ranked 16th and look at the trouble the IDF had with Iran.
On the other hand-- NATO member Turkiye -- with its 88m people -- is ranked 9th militarily in the world; by contrast Canada is ranked at 28.
In addition, Turkiye would receive military assistance from NATO (by treaty) and South Korea (by friendship) in the event of any conflict with Israel. Ankara and Seoul share a special bond forged together during the Korean War. To this day, whenever their sports teams meet (Tae Kwon Do, football, basketball, etc), there is no rowdiness or antipathy between fans, but rather mutual admiration and trust.
South Korea is ranked five out of 145 countries in the Global Firepower Index (GFI) and has powerful non-nuclear weapons and is the envy of other mini-superpowers.
North Korea is ranked 31.
Israel would not stand much of a chance against Turkiye unless the Israeli Death Forces (IDF) idiotically used their nukes whose radioactive fallout would affect their own tiny country.
And Turkiye may respond by requesting use of the nuclear B61s via Article V of the NATO treaty.
