That is a possibility.

Trump's meetings with Xi, Abe, and Modi have gone well.

By contrast, his meetings with Merkel and Macron have been disasters, although Macron has invited him to Paris for Bastille Day. 

Trump seems to get along better with Asian leaders than European ones.

Trump would help gain support of key allies such as the U.K., Germany, and France if he would just offer lip service for the Paris Accord.  Even NK is astute enough to see that their interests are advanced by at least giving superficial support for measures designed to control climate change.

With very great respect, I would suggest that Kim, Xi, Putin, Assad, and various terrorist leaders are greater threats to world peace than Trump.

But you are 100% correct to suggest that Trump's childish rants and failure to appreciate how the political/security consequences of climate change denial are undermining US security and they have to stop or Trump needs to go.
