Hamas isn’t the problem. Both Hamas and the PA tried peace and a 2-state solution along 1967 borders. The Arab League offered peace and normalization to Israel on similar terms in 2002. Israel, specifically the right which keeps winning elections, rejected all peace attempts. Netanyahu’s party the Likud adheres to the ideology of Jabotinsky and refuses any Palestinian statehood at all:

[It is the] iron law of every colonizing movement, a law which knows of no exceptions, a law which existed in all times and under all circumstances. If you wish to colonize a land in which people are already living, you must provide a garrison on your behalf. Or else – or else, give up your colonization, for without an armed force which will render physically impossible any attempts to destroy or prevent this colonization, colonization is impossible, not “difficult”, not “dangerous” but IMPOSSIBLE! … Zionism is a colonizing adventure and therefore it stands or falls by the question of armed force. It is important to build, it is important to speak Hebrew, but, unfortunately, it is even more important to be able to shoot – or else I am through with playing at colonialization.

As quoted by Lenni Brenner, in The Iron Wall: Zionist Revisionism from Jabotinsky to Shamir (1984), where the quotation is cited as being from “The Iron Law”

Jabotinsky wanted to go further and claim both banks of the Jordan river. Today in Israel talks of annexing Lebanon, Syria and beyond as part of Greater Israel are becoming more mainstream.
