You got the first half right, but the second wrong.

Netanyahu’s government doesn’t give a shit about Hamas. They never have. Hamas is just a convenient excuse for them to pursue their real goal, which is and has been all along to kill, drive out or subjugate every single Palestinian, because they believe that Palestine has no right to exist at all and that everything from the river to the sea should be theirs, no matter how many lives they have to destroy along the way.
