Your oversimplified what I wrote and then from that highly reductive take you built an overcomplicated argument.

If certain statements are reliably not followed by action that further the state objectives then “they’re all talk”, if they are reliably followed by such action then they’re not.

Whilst statements by themselves can logically neither be accepted as trully meant nor dismissed as “just talk” in the absence of any track record at all (i.e. first time your hear such things from such people) because there has not yet been time to observe if they’re followed by action or inaction leading to a conclusion about the statements being meant or “just talk”, when there is a track record one can most certainly extrapolate the likelihood of such statements now being meant or “just talk” if in the past such actors reliably followed such statements with action or inaction.

As it so happen, US Administrations, Democrat and Republican, including those were Biden was, invariably followed statements were they claimed they were going to make Israel do or not do something, with no effective action towards their state objectives or even with actions which were counter those objectives.

In fact the there not being a 2 state solution in Palestine even though various US Adminidtrations claimed to favour it is exactly because NOT ONCE has any of those Administrations acted to punish the Israeli Government for their actions against the Oslo Agreements, quite the contrary: Israel has kept being supported economically and military all the while it acted against the wished stated by the various US Administrations.

It is thus entirelly logical to expect that statements from the US Administration about imposing anything on Israel are “just talk”, and totally illogical to ignore the track record of decades of “stating one objective and the acting in opposition to it” by the US with regards to Israel.
