The Netherlands has US nukes: https://nl.m.wikipedia.org/wiki/Vliegbasis_Volkel

Apparently also Belgium , Italy, Turkey, Germany have the same type.

Yes, but these are US nukes, under complete US control. US decides when and where to use them. In other words, these countries are launch sites for the US army.

What I had in mind are nukes under the jurisdiction of a country (such as France or UK in Europe)
