Wow @doodlebear, that was a quick response! Thank you for the book suggestion. I will look into it.

That is very interesting about German leftists, and "revanchist," as a sort of acceptable "retaliating, especially by a nation or group to regain lost territory or standing; revenge."

It actually seems to tie into what Clinton said, regarding Putin, back in 2014, that is quoted in the article. It's a game to them, and it's been used successfully before.

It's true that history has a way of repeating itself, and so to know what's ahead, we have to know what's behind.

Thank you for your in-depth response, and book recommendation. Much appreciated.
