No, they didn't apply any genuine pressure, just empty rhetoric while continuing to provide billions worth of weapons unconditionally while Netanyahu ignored every "red line" with zero consequences. Biden is a self-proclamed Zionist, he had no issue with the genocide. All the empty rhetoric was just theater

The rhetoric coming out of the White House, when it has been focused on peace or restraint, rather than continuous war, has been undercut at every turn by its actions. The constant supply of weapons — $17.9 billion of bullets, bombs, shells, and other military aid in the past year — has allowed Israel to keep waging its war on Gaza, and in recent weeks, expand that war to Lebanon and threaten to escalate its conflict with Iran. Despite documentation of U.S. weapons being used in probable war crimes, and credible allegations that Israel is committing genocide in its war on Gaza, the bombs have continued to flow.
