All she had to say was:
"Israel had a right to defend itself, however after their indescriminate attacks on civillians in Gaza, not just the men, but also, the women and children, an act that clearly and undeniably violate internation laws, Israel no longer have the right to defend itself. I will immediately call on President Biden to suspend any and all military aid to Israel. Futhermore, sanctions will be imposed on Israel until they cease their indiscriminate killings."
Then actually make Biden do it. Kneecap him if he doesn't.
And for domestic policy:
"As president, I ensure every American has access to healthcare by calling on Congress to pass legislation that would make Medicare For All a reality in America."
There, campaign saved. Just keep up the public appearances, talk to people, and win the election.
But unfortunately, that's a different timeline. This timeline is fucked.
