No one said it was going to be an easy chair to sit in. This man ran for president on being a career politician who knew how to get stuff done and work with people on both sides of the political spectrum. Sure, he had some good wins domestically like the infrastructure bill and the chips act. But this man is losing all credibility on the world stage. Even the most hard line Zionist presidents in the past have been able to control Israel, Biden cannot. Putin has never been so brazen and openly defiant in the past. And now, organizations like BRICS are being formed in light of these kinds of weaknesses America is displaying. If you're the leader of the richest and most powerful nation on the world and you can't control any situation you're directly involved in except to bitch about it in private, then you're not a competent leader. Leaders really need to be help to a much higher standard, especially when the stakes are so high.
Regarding your comment on the weapons sale to Israel. Bernie isn't Biden. Biden holds a lot more executive authority and his words carry a lot more weight than a senator, even one as popular and well known as Bernie. This wouldn't even be that unpopular of a decision either. As of February, two thirds of Americans support the decision for Biden to call for a ceasefire. And these numbers have been more or less consistent for the past year.
If you want to believe that then that's your choice. Just don't act surprised when other American proxies decide to lobby American politics so heavily in their favor like Israel is currently doing. The past year has shown the world just how susceptible American politicians are to foreign interference, and that includes presidents.
If that were true then US would have had things like universal healthcare a long time ago.
