To get hostages back? Hostage exchange.

To dismantling Hamas and armed resistance from Palestinians? Stop ethnically cleansing the West Bank and remove the boot from their necks so that people in Gaza see that there is a better way and that going down fighting is not the only choice.

Plenty of alternatives to death and destruction when those are not the actual goal itself. Of course those alternatives do not go hand in hand with the idea of an ethnically-cleansed Greater Israel, so here we are.
