They can protest all they want.
The decisions on how to fight are made in Gaza and Israel.
To tone down the level of combat will only happen with hostage release.
It seems there are no hostages to release except possibly in parts in body bags. Hamas will want to trade the "hostages" for hundreds of Hamas in Israel jails and they have to be safely conveyed to other countries before the dead Israelis are given up and then he meaning of taquiya will b e once again demonstrated. .
