This emboldens the bully Israel. Now they know that no matter who they pick on, they will never feel any real counter-attacks because the US will stop them all. This encourages them to continue their attacks and to pick new fights because there will never be any consequences. If Biden wants to encourage Netanyahu to stop his wars of aggression, he needs to make Israel second guess their attacks.

This move absolutely counters his message for a ceasefire. This will embolden them to keep fighting.
