Kyiv could rapidly develop a rudimentary weapon similar to that dropped on Nagasaki in 1945 to stop Russia if the US cuts military aid, it has been suggested
Ukraine is the only country in the world that has the full moral authority to develop nuclear weapons. We are the only country to give up nukes and look where that got us.
That being said "moral authority" isn't worth shit in this world.
South Korea, Poland and the Baltic nations should honestly try and develop their own nukes too.
