If there's a competitive party in the Knesset that is actively against bombing Gaza, sure.
But literally the leader of the opposition in the Knesset is *fully in support* of the IDF's actions so far.
As it stands, Likud has had a strong grip on the Knesset for a long time, despite not really having a mandate of popular support.
Even when opposition parties have won a plurality, war hawks like Netanyahu and Sharon have still been able to build Likud-run coalitions.
