Justins decision post-Trump is that of an ideologue, pure and simple.  Liberals used to hate ideologues, not all that long ago, today..well...not so much.  Funny how the school of liberal fish can suddenly change direction en masse.

The climate is changing, and now the political climate has changed.  Figurehead leaders who don't adapt to current conditions on the ground will be left looking for their coveted UN position in 2019 with a newly minted PM and generations of youth left to shoulder the burden of Justin's popularity contest.

I look forward to Justin pressuring the US and China to join the climate change fight.  Snicker...darn...almost got that out with a straight face!
