Well I have always believed that Hamas is a terror group and up to no good. But that said, how do you envision them 'capitulating'? They may not remain in power, but they will still exist as an extremist group. The Hamas guys are all replaceable. I have no problem with Hamas being decapitated or disemboweled. What I do have a problem with is Palestinian civilians, especially kids being decapitated and disemboweled, which is what is happening today. And that is not an exaggeration because I posted a graphic pic a couple pages ago. Such violence will only create MORE terror, not less. Infact, we have lessons we learned from the 20 year war on terror, where it actually created more terror, not less. So guarantee this will never happen again? I can guarantee you that this will happen again, and worse, 10,000%, in one form or another, if Israel keeps going down this road, which they most certainly are. Infact, they have already succeeded in creating many terrorists for the future.
Firstly, the analogy with the indigenous folks is actually working against your argument for a one state solution, because that is precisely what we have here. A one state solution. Indigenous people are citizens of Canada and they can do whatever they want, the same as us, after decades of slaughtering each other.
Secondly, the 2 state solution is dead. For a 2 state solution to happen we need 3 primary things:
1. Israel needs to agree: Israel won't. Infact, they have said that they won't. Infact here is Bibi, telling you that there will be no Palestinian state. So please tell me, how is a 2 state solution possible, when Bibi has a "no Palestinian statehood" platform. Infact, his Likud charter that I highlighted in my last response, shows that he wants to keep building settlements and that he only will agree to Israeli sovereignty between Jordan and the sea. (River to the sea).
2. Palestine needs to agree: For Palestine to agree, they need absolute independence. Politically, economically, militarily and morally. Forget land for a second. Will Israel agree to such independence? Not possible, given the above declaration that from the river to the sea, Bibi will only agree to Israeli sovereignty.
3. There needs to be contiguous land. Here is the map of Israel with the Palestinian areas highlighted in white. Please tell me how a 2 state solution can be formed with this current scenario:

So once again, when you talk about 2-state solutions, Hamas surrendering etc., these are disingenuous and not well thought out statements where you are basically spouting talking points, knowing full well, that what you are really supporting is ethnic cleansing/genocide of the Palestinians. Atleast, Mandrill said it out loud that he thinks the Palestinians should just leave to Egypt and Jordan. So if that is what you think, you should say that out loud, but atleast have the honesty to acknowledge the injustice you are supporting instead of empty words. 
So given this scenario, the only solution that will work, is steps towards a one-state solution. Baby steps, towards a one state solution to eventually happen a few decades later.
The only other option is genocide. So you decide, whether you want to be on the side of genocide or on the side of taking those steps necessary to integrate the Palestinians as equal citizens, into the only viable state we have right now, which is Israel.
