Literally Kremlin propaganda. Trump did a post Putin interview with Tucker Carlson.
In his defense of his naive opposition to NATO Tucker just "randomly" picked Montenegro as country that he wouldn't want his son to have to fight a war to defend.
And Trump enthusiastically agrees saying Montenegro a tiny country with very aggressive people. Aggressive people? “They may get aggressive, and, congratulations, you’re in World War III”

I was watching and thinking, "How the hell did you even come up with Montenegro as your example?"

Come to find out Russia had been accused of organizing a coup in 2016 to assassinate the Prime Minister of Montenegro and install a pro-Russia prime minister. And Montenegro just joined NATO last year.

You know Trump (probably Tucker too) didn't even know Montenegro existed until a few days ago
