One could argue that, but that would be their eagerness to ignore and dismiss important details of Ukraine's founding legal documents that made their independence possible in the first place.
If one reads the Declaration on the State Sovereignty of Ukraine from 1990 [1], one will find it in Chapter IX: "The Ukrainian SSR solemnly declares its intention to become a permanently neutral state in the future, which does not participate in military blocs and adheres to three non-nuclear principles: not to accept, produce or acquire nuclear weapons".
Ukraine's constitutional sovereignty has always been and still is predicated on respecting these conditions, but a whole lot of politicians, foreign and domestic, want you to believe otherwise because it serves their political goals.
