This is a pretty big shift for the US, and it means the pressure is finally starting to really register with Biden. If the "uncommited" results in the Michigan primary were enough to get his attention, recent polling that puts him 8 points behind Trump likely changed the debate for the foreseeable future.
Biden is playing diplomatic chess. Netanyahu warned the US before the vote that Israel would not participate in a meeting if the US didn't use its veto. So, now the US didn't. BTW, Hamas launched rockets at Ashdod right before the Security Council voted confirming its status as an equal fighting party in the war before a ceasefire.
Of course the sentence is relevant. I'm not sure why I should bother writing a reply to you when you apparently stop reading them after the first word. Have a good day.
The best time to abstain would have been decades ago, but the second-best time is now. Don't let the perfect be the enemy of the good; this was a good choice.
Edit: The downvotes are hard to interpret. Do people think the US abstaining (and thus allowing the resolution to pass) was not a good choice?
