In reality, the US isn't vowing to defend the state of Israel, the US is vowing to help Israel attack other countries. If you're pledging unconditional support to an extremely belligerent aggressor while it commits the most demented acts of aggression imaginable, all you're doing is condoning those acts of aggression and making sure it will suffer no consequences when it conducts more of them.
A kevlar vest stops being a tool of defense when you wear one to prevent yourself from being stopped by police while conducting a mass shooting.
