Unfortunately, that isn't likely to happen. Netanyahu has, to date, handled Trump deftly and Rubio's current presence in Israel seems to be aimed at offering support to the ground offensive, not opposition. I honestly have no idea what kind of backlash it would take to shake U.S. support for this genocide.
Currently there is war, peace is out of the window. First step is to stop the war, second step is to make both side actually negotiate.
It was attempted by Clinton a while ago but assassinations from mossad and hamas prevented the process to success.
To be honest, politicians have failed us too many times for my sad brain to believe that there will be a good outcome.
Most probably Israel society will keep radicalizing itself, Palestinians will be killed and Gaza bombed/annexed leading to the death of both Palestinian and Israeli civilization. Palestinian will be all dead and Israeli will have become in all manner what they initially sought to destroy, literal nazi.
I’d even bet that death by zyklon is more human that seeing your family and yourself getting slowly hungered to death. And contrary to nazi Germany, no Israeli can pretend to not know what’s going on.
