Should Ukraine build the bomb? How would you feel if they did?
Trump has stated he will cut American aid to Ukraine, which makes a majority of total aid. Recently Zelensky stated that if Ukraine's only hope for sovereignty is its own nuclear arsenal, they will build it.
I think nuclear deterant is the only thing that has a chance of working for countries that aren't military super powers, and even military super powers have them for a reason. And a country having to rely on benevolence of other countries leaves too many things to chance for nations that wish to be sovereign.
Are you implying that russia is a military super power? Their performance in ukraine has shown they are a paper tiger with a few nukes up their sleeve from back when the soviet union was actually a major player.
