The smartest move, if you actually care about ending the war in the Middle East, is to read between the lines of what Kamala is saying. She cares about *HOW* Israel defends itself. She wants a ceasefire. These are the things that tell you that she agrees with you and wants this to stop.
If you're smart, you'll recognize the situation she's in and put your trust in her that, once she secures the power of the office, she will use that power to negotiate a ceasefire.
