That Israel has long had an American propaganda campaign and a well funded PAC is not a secret.
As do Muslims with CAIR and the like.
My guess is Netanyahu has played Trump like a fiddle. He tried to coax Obama into attacking Iran.
A war with the Tehran regime was always inevitable. Would that Obama had heeded the coaxing then, it would have been an easier war. Iran greatly developed its missile and drone capabilities since the days of Obama. Instead, he negotiated a rotten deal that greatly favored the Ayatollahs, giving them sanction relief and pallets of cash for very little in terms of concessions.
It is all well beyond an issue of antisemitism. Israel has played the victim to US conservatives while colonizing the West Back pushing Palestinians off their land. Jews from around the world have gone to Israel to get 'free' land.
Judea and Samaria is not Arab land. If it was, they would have a native land for it, instead of using synthetic neologisms like "West Bank" or Greco-Roman colonial names like "Palestine" that cannot even be pronounced using Arabic phonemes. Same goes for "their" cities like "Nablus" which is a corruption of Greek "Neapolis" (New Town). Again, they can't say 'p'.
American politicians him Bibi.
It helps that he speaks excellent English owing to his time studying at MIT.
