This is a fascinating survey of the political realities of contemporary Israel from the perspective of an Israeli leftist. Although I don’t endorse every view expressed by the author I do consider this piece to be an excellent tool to understand the internal political influences pushing and pulling in Israel right now.
Is that really up to debate? According to Israel’s Declaration of Independence, it needs to cover all of Eretz Yisrael (it can cover more, though):
