A US political feud has escalated into direct accusations that pro-Israel commentators put a foreign country ahead of America, a sign of how bitter the fight over Israel has become on the American right and left.

• Cenk Uygur accused Ben Shapiro of pushing Israeli talking points while questioning the loyalty of immigrants and their families.
• The charge is that Israel gets US money, US soldiers, and deep military ties, and that American politicians are bought to keep it that way.
• Shapiro's side framed the argument around whether immigrant-descended commentators actually care about the country.
• The word "traitor" is now being thrown in both directions, with each side warning the other that the accusation can be turned around.

Outlook: Expect the loyalty-and-Israel fight to keep spreading through American media, with immigration and foreign aid as the flashpoints.
