"You can't tell us how Biden could have stopped Israel"
Possibly because that noble form of behavior would not appear to exist withing the current framework of the Democrat Establishment, which just seeks perpetuation of its own power.
You are conditioned, through the need to perpetuate the power of your beloved party, to limit the power of the Chief Executive of the most powerful nation on Earth to that of general platitudes backed-up by the threat of either brute force or passive do-nothingism.
"If there is debate among dominant elites (re: the Democrat Establishment), it will be reflected within the media, which in this narrow sense, may adopt an "adversarial stance" with regard to those holding office, reflecting elite dissatisfaction with current policy." -Noam Chomsky, Manufacturing Consent
No real adversarial stance from major pro and anti-Democrat media groups. MAGAts generally agree with the stance of the Democrat establishment, and the only disagreement is when it is best suited to leverage their own party's extremist, domestic political agenda.
When it comes to Israel, no meaningful debate currently exists within the Democrat establishment.
