It occurs to me that nuclear proliferation is a very bad argument against nuclear power.

Why? Very simple: the biggest offenders in terms of CO2 emissions and pollution are nations which already either have nuclear weapons, or could build them if they wanted. Out of the top 8 emitters, five are already nuclear powers, and the other three are not because they choose not to be. The US, Russia, China, UK, India, Canada, Japan, Germany. Just those 8 account for about 75% of the global CO2 output annually.
