It started with the Cold War, where Palestine (and the Arab world at large) was generally supported by the Soviets while Israel was at least theoretically supposed to be in America's corner (in practice, they pursued their own interests). Got bad enough that there was at least one major direct confrontation between the Israeli Air Force & Soviet fighters helping out the Egyptians, which the Israelis won. Also, enough Jews wanted to GTFO of the Soviet Union and were banned from doing so until cracks started emerging in the 1970s that a term had to be invented for it, 'refusenik'.

The Soviets had plenty of interest in propagating pro-Palestinian, anti-Israel propaganda back then while the American establishment was firmly aligned with Jews in general: Democrats have pretty much always counted them as a key supporting demographic since FDR's day because they're urban and on-average educated immigrants or the descendants of immigrants with a socialistic bent, while in the Republican Party Jewish neocons were able to sideline actual American nationalists like the John Birch Society with the help of shabbos goyim like the Buckleys. (I think it's noteworthy that no matter how hard Republicans suck up to American Jews, as a voting bloc they have literally never once voted in the majority for the GOP, not even for theoretically universally popular candidates like Eisenhower or Reagan.) Since both parties' establishments were staunch supporters of Israel and this status quo has only begun to be challenged very recently, it was only natural that anti-Israeli forces were going to be anti-American by nature as well.

Post-Cold War and more relevant to the younger generations like the lunatic in that video above, it's just a case of rootless blood-red Western Jews' golem slipping the leash and turning on them. Only one thing can happen when you do your damndest over several generations to turn your students into frothing-at-the-mouth Red Guard wannabees with a programmed murderous hatred of anything that smacks of 'colonialism' or 'whiteness', while Cousin Akiva on the other side of the world is busy building settlements and displacing the brown(er) locals.
