It is a core problem. The Pales realize Israel doesn't really want to negotiate a peace. Nevertheless, Hamas's real goal is to destroy a Jewish state. You can't have peace with Hamas. In a sense Likud and Hamas need each other like the Hatfields and McCoys.
The comparison between Likud and Hamas is impossible, plus its not only Likud, its 97% of the population in Israel against Hamas.
The FULL responsibility for zero peace negotiation tied with the preconditions just for negotiating, the Pals only try to squeeze and evade peace, it was before, and it will be in the future unless something will change, and I agree Hamas are incapable of peace, but the only way to change it is by eliminating Hamas off the equation and helping the Pals reach the bright 'Arab Spring' future, all past negotiation failed because of the Pals refusal not Israel.
Last 9 month negotiation Israel agreed for a preconditions froze the settlements and released 350 terrorists (convicted killers as well) and that peace talk reached no where, Abbas refused to continue without more preconditions again, and blew it up, later on he made pact with Hamas.
Likud needs Hamas to legitimize its claim that there can be no two state solution. All Israel ever agrees to is 'temporary halts to settlements." I don't believe all Israelis are committed to ethnically cleansing the west bank or establishing an apartheid regiem, but Likud's coaltion does. Hamas needs Likud to show the Palestinians there can be no peace with Zionists.
However, even without Likud, and a return to actually trying to form a demilitarized Pale state in the west bank, Hamas would be undeterred. Which is why the vast maj of Israelis support the gaza military operation.
I don't see Israel as ever being able to rid itself of Hamas without ending the appropriation of land, and committing to a pale state in the west bank, with Jordan.
But, hell, lets just end it. Israel's already taken the land. Let's stop pretending you're capable of honest dialogue

Here again you compare Likud to Hamas, Likud won the primaries and posses the biggest part of the departments but nothing like Hamas which posses ALL of the government in Gaza,
Here you can see the Knesset (Israeli Parliament)
Hamas did not won a legitimate government election, and considered the "only" faction ruling Gaza, and declared all over the world as Terrorist Organization(US: No negotiation with Terror remember?)
With this being said, I want to list all hostile terrorist organization/groups except Hamas:
PIJ,PLO,PFLP,TPRC,DFLP,PLF,ALF,VPLW,PPSF,PAF,Fatah,Tanzim,Fatah-SOG,Force-17,AAR-Brigade,BSO,AAM-Brigades,PFLP-GC,Fatah AI,Jund Ansar Allah,AOI,Jaljalat,Jahafil Filastin,Hezbullah,ISIS,ISIL - And god knows what else..so we don't need them, in fact the world would be a better place without them.
Another point is that Hamas always win, dead kids photos or victory spoils to political support in Gaza, we don't need them, trust me.
So far Israel is always considered apartheid by the pro-Pals, but I never heard any reason why so, the "ethnically cleansing" is just a poor de-legitimization nothing beyond that, the West Bank is Israeli territory - not Palestinian, the fact Palestinians living in the West Bank at this very moment is absurd but they posses West Bank ID which means they are allowed to stay there but not enter the rest of Israel without valid permits, and the same way I can't go to the US and live without a Visa - same for them, and its the same all over the world, Israel also evacuate Israeli settlements - do you know that?
Israel has right and left wingers with freedom of speech and all rights plus special rights for declared minorities, 97% is also Israeli Arabs for example, and this also include the left wing, all your claims come from lack of knowledge about Israel and lack of knowledge about the Palestinians, lets not mention the entire conflict, So I don't see why you bother analyze the situation or even compare..but hell, you are a pro-Palestinians so lets stop pretending you even capable of a honest dialogue.
