US would join only Syria and Nicaragua on climate accord 'no' list

Only other UN members not party to Paris agreement never signed up, but for reasons of war and principle, not disbelief

Assuming the US does, as expected, pull out of the historic Paris agreement on climate change, it will join a very small list of countries with which it has little else in common in terms of emissions.

The only other UN members not signed up are Nicaragua and Syria, which both chose not to enter into the climate accord in the first place.
