It is confusing to me that Americans serve in the IDF. But I'm not convinced that banning them from reentering the US is justified. It isn't the only time that Americans have served in foreign armies. (I have watched a lot of Tucker's shows, and I think he's said something along those lines although I can't remember the exact verbiage) The flying tigers in WW2 and Americans joining the French foreign legion come to mind as examples.
I appreciate Tucker raising this issue and asking tough questions. It’s unfortunate that his inquiries have led to accusations of antisemitism. His exchange with Cruz was particularly revealing.
Israel was created by the British. Not sure why that region, because Ashkenazi Jews are converts from Khazaria - now the Ukraine / Georgia areas. They are mostly Eastern-European. They are not the Jews from the Bible - so the area where Israel settled was not their homeland.

Kiev is in the upper left corner of the map.
The Khazars were a predominantly Turkic-speaking people. They established a powerful empire in Central Asia and Eastern Europe, known as the Khazar Khaganate, which existed from the 7th to the 10th centuries CE. While their origins are debated, they are widely believed to have migrated from Central Asia and were part of the broader Turkic migrations that shaped the region.
Now we know why Erdogan collaborates with Israel.
The "13th tribe" theory posits that Ashkenazi Jews are primarily descended from Khazars, a Turkic people who converted to Judaism in the 8th century, rather than from the historical Israelites. This theory, popularized by Arthur Koestler's 1976 book "The Thirteenth Tribe," suggests a Khazar migration westward into Europe as the Khazar Khaganate declined, contributing significantly to the Ashkenazi gene pool.
