There's no space-time American hippie liberals involved. They're not smart for time travel.
What we have here is history repeating itself. National SOCIALISTS put Jews in gas chambers and killed them.
Democratic SOCISLISTS are chanting with the Palestinians "From the river to the sea, Palestine will be free" or accurately restated "From the Jordan River to the Mediterranean Sea the land of Israel will be rid of all of the Jews as a start on their campaign to rid the planet of the Jews". Palestinians do not want that land, if they did they would have accepted one of the 658,766,586,846,654.5 offers to create a two-state solution years ago. They just want to obey Allah and kill all of the Jews, nothing more, nothing less.
And the American hippies liberals are more than willing to go along with their plan because once a socialist Jew hater, always a socialist Jew hater. It's in their DNA. Both Marx and Hitler were self-hating Jews who wanted all Jews exterminated. Marx had no power but Hitler (his devotee) did. Hitler made alliances with Muslims because they both wanted to exterminate the Jews.
However, I am not sure if the American hippie liberals fully understand the goal of Hamas, Hezbollah, the Muslim Brotherhood, Ilhan Omar, etc. Oops did I say Ilhan Omar??? She's part of it.
