Since the start of the conflict after the 7 October attacks, the president has been caught in a vice, forced to make Middle East policy choices that anger key parts of his coalition.
But the Biden administration is treading carefully when it comes to substantive policy shifts. And despite this week's domestic pressure, the White House has largely remained set on its current course.
