Hard to buy that conclusion. 35 countries with existing or under construction nuclear power. But only 9 countries with nuclear weapons, 2 of which do not even have any nuclear power. And when you go through the history countries seeking nuclear weapons don't start by building nuclear power, they tend to go straight to fit for purpose reactors dedicated to producing plutonium (e.g. Dimona or Hanford or the French and English equivalents) or to enrichment plants (e.g. as Pakistan did long before it ever had a civilian power plant).
