>>The NATO funding thing isn't as clear (to me) as the numbers seem to show.
True. But I suspect Trump's view would be that the flouting of NATO's 2% defense "guideline" by most European nations is credible evidence of what will happen in the Paris agreement, with the US again ending up carrying much of the cost while its biggest industrial competitors either award themselves zero cost and zero reduced emissions or simply flout their NDC while the US is scolded and castigated for ruining the planet unless it stumps up vast carbon fees for others to consume.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
