He continually is pushing the boundaries of racism. Can't tell if this is an attempt to distract from the Russia bounties story or not...
It's simply a fascist pushing fascist policies.
Don't assume any deeper meaning or planning behind it.
The 20th century started with Monarchy collapsing in Europe and that was followed up by a conflict between three routes.
Liberal democracy, communism, and fascism.
Now fascism is back, with Russia and the US as the main proponents and China to an extent.
In the age of climate change, it isn't all that surprising to see people fall back on nationalist and racist worldviews to justify violently defending a status quo that works out well for them.
Make no mistake, all of this is about normalizing the killing of hundreds of millions of climate refugees.
Pluralist and humanist values, human rights, liberal international institutions... all of these need to be destroyed by the time climate change really hits so countries can justify genocides by vilifying "the other".
This trend won't be over when Trump is gone. Based on the fact that barely any countries are actually doing anything to stop climate change, the only logical conclusion is that most countries are fine with the idea of preparing to fend off (kill) the hundred of millions of climate refugees that will keep coming over the next century.
What we are currently seeing is liberal values being dropped at the first sign of trouble.
