This is taken from a press conference where Biden is saying that Jordan and the US are literally attempting to get Israel to stop attacking Rafah via a hostage deal where they get some Israelis returned in exchange for halting the offensive on Rafah. https://piped.video/watch?v=aZUshbIWkis& @0:48 - 1:06

Biden & his administration have enabled the genocide against Palestinians to a large degree, and their attempts to get Israel to stop attacking Rafah are highly likely to be ineffectual, but this is an obviously propagandized framing of a common occurrence: Biden, a man in his 80s, misspeaking. Stuff like this weakens the arguments against Liberals because it is attacking a strawman. Attack them on the actual merits, not an 82 year old president known for misspeaking referring to the actions of a military ally as "our operation" before correcting himself quickly afterward.

Could this be evidence of a conspiracy where somehow the US did the attack on Rafah? I guess? Sure, it's possible. Is it the only or even the most likely explanation? No, obviously not.
