A growing part of the American right is turning on Trump's Israel policy, arguing he put a foreign country ahead of his own voters.

• Trump has restored maximum pressure on Iran and promised the toughest sanctions possible.
• He described the tie between the US and Israel as an unbreakable bond, and was praised as the best friend Israel has ever had in the White House.
• The pushback: a president's only unbreakable bond should be with his own citizens, not another country.
• Every recent president has backed Israel, so the claim of being the "greatest friend" is read as a signal of something more.

Outlook: Expect more open conflict inside the American right over Israel policy and any move toward confrontation with Iran.
