There is zero evidence for it, only conjecture, just like your post reads as an “imagine that” or “I wish that” in all but actually using those specific words.
Sure, we can all wonder about the possibilities, and even presume that it might (based on nothing but some personal sympathy for a specific american political force) but we’re not government members and are not telling it to the Press.
Might is the domain of fantasy, a universe away from is.
The “enemy from outside” is quite the Propaganda staple of Fascists, including the Nazis, and variants of it have repeatedly been used by this Israeli administration to justify their current, Nazi-like mass murder along etnic lines, so an Israeli government member “casualy” sharing with journalists such evidence-free wonderings - stated as fact, no less - seems far too convenient and within that pattern to be a mere accident.
You did have Schumer calling for elections in Israel. Biden invited the opposition party to discussions in America against the protestations of Netanyahu.
There are a lot of mixed messages with the continued arms shipments, but it seems obvious there is some movement in the Biden administration to find a more agreeable negotiation partner. I doubt they’ll go outside of the established democratic processes, but again, I won’t be surprised if there is some pressure for Netanyahu to step down.
All the actions of the Biden Administration have been on the side of supporting to the maximum extent Israel, its Administration and its actions, with the only actions that ever so slightly deviated from that - such as the food airdrops - being so ridiculously small (solving about 1% of the problem) that they do not seem to be meant to solve the problem at all, and hence cannot be explained as motivated nu that, with the most likely explanation being that they’re for managing image to help Biden’s reelection chances, a selfish rather than selfless purpose.
Sure, the talk is often different, for the simple reason that talk is cheap and as long as what makes any real difference - actions - carries on as it is, then the talk is entirelly irrelevant and only has the informational value of showing that the Biden Administration are usual and shameless liars.
