The world, and many politicians, feel that a Two-State Solution in the Middle East is the only chance for peace. Without getting into the question whether we can actually trust our enemies and believe them that they may actually lay down their weapons, we must also deal with the question, what does Judaism say on this important topic?

Why did the religious-Zionist camp take upon itself the commandment of the Land of Israel as such a primary and important project, while ignoring all the other commandments?
