Haniya never accepted a two-state solution. You have to read his words: he accepted the notion of a resolution that saw a Palestinian state in the 1967 borders with a right of return and East Jerusalem for Palestine. However, every time Hamas talks about these "resolutions" they use the word hudna, which is still only a temporary truce that they are willing to execute while they are too weak to destroy Israel.
There may be some people in Hamas who are reasonable on this point, but they haven't made that point clear and they haven't used language that any reasonable government would be ready to rely upon. If you believe that Haniya and Meshal have unequivocally stated that they are willing to enter into a binding treaty with Israel (not just a hudna ), please provide some documentary evidence.
You also believe the lie that Hamas is a political party. They aren't. If they were a political party, they would oversee elections and be willing to relinquish control if they lost. Any "political party" that doesn't do that is an authoritarian or totalitarian organization.
Your statements reflect a certain naivete in your willingness to engage in moral equivalency. It is one thing for Likud's charter to say that Jewish settlement in Judea and Samaria is to be encouraged or that the Jordan River is Israel's boundary - these are essentially negotiating positions. I could believe the same about Hamas' charter were it not for the genocidal nature of it, which is completely different from anything Likud has ever said: "The time will not come until Muslims will fight the Jews, until the Jews hide behind rocks and trees, which will cry: O Muslim! There is a Jew hiding behind me, come on and kill him!"
If Hamas wanted to moderate, it had ample time to do so. Instead, since its takeover of Gaza in 2007 (which saw over 500 Fatah members murdered), it has regularly fired rockets at Israel, fought a few inconclusive wars, and dug in more extensively to prepare for the next one.
I guess the good news is that Israel seems to understand, after seeing how much Hamas was preparing for future wars rather than attempting to do anything for Gaza's civilians, that it needs to uproot the organization. Perhaps it can hand Gaza over to Fatah and lift the blockade, which would go a lot farther to achieving a two-state solution than talking to an organization that has stated goals of killing all Jews.
May the IDF prevail!
