Like what most of what Trump claims, that was also a lie.
Here are the facts: https://www.factcheck.org/2019/12/factchecking-trumps-nato-remarks/
And here is more on Trump’s threat to leave NATO: https://www.atlanticcouncil.org/blogs/natosource/trump-confirms-he-threatened-to-withdraw-from-nato/
There should be no doubt that this pleased Putin no end, and may even have been a factor in his attack on Ukraine, but don’t expect Trump supporters to understand that!
As usual, Trump doesn’t put much thinking behind his statements, nor do his fans put much intellect behind their blind support for such an incompetent, selfish and treasonous low-life.

Let’s not forget how Trump even tried to weaken NATO! WHY? Was it just another silly idea he cooked up on his own, or perhaps more likely a request from Putin?

Hey guys just dropped into Jorg’s happy opinion site. I don’t think any of us are privy to any exclusive info but rather glean what we all can from various sources we deem reliable. I actually think Putin had no expectations of Trump other than annoying the status quo between Democrats and Republicans which have only minor differences when it comes to military desires for ‘Full Spectrum Dominance” with the US the big dog around the globe. Under Trump’s watch the Us commenced the transfer of lethal aid to Ukraine. The continued goading in Russia went on unabated regardless of our chief executive in the oval office. I have the Chinese proposal if you guys are interested. It’s pretty general and calls for working towards a ‘gradual ceasefire’ what ever the hell that is. Anyhow it’s the first intelligent approach from a jamor player. Tune in.
Cheers all, Mike C.

This is not only well worth repeating, Ray, but necessary, so we don’t forget! I realize such embarrassing truth is very inconvenient for Republicans, – but nothing compared to how “inconvenient” Trump has been for the steadily increasing majority of us, and continue to be! And utter shame on all those slow learners dumb enough, and un-American enough, to continue to support this incompetent, selfish, treasonous liar. He is still dangerous, whether his supporters understand that, or not!
