"...Palestine does not need anyone's permission to be a state."
True.
What they need is a time-machine, to travel back to May 14, 1948, and to declare Statehood and Independence on the very day that the Mandate expired.
What they need is a time-machine, to travel back to 1947-1948, and to prevent their younger selves (and parents and grandparents) from abandoning their homes and lands, and to stand their ground rather than running away.
What they need is a time-machine, to travel back to 1967, and to prevent their Jordanian and Egyptian and Syrian brethren and co-religionists and masters from attacking Israel, and giving Israel the excuse to capture lands and to hold them as spoils of war.
What they need is a time-machine, to un-do multiple Bad Decisions, in choosing not to negotiate and compromise with the Israelis, while the Israelis were still in a mood to compromise.
What they need is a time-machine, to prevent themselves from conducting years-long campaigns of terror-bombing within Israel, and to prevent their miscreant sympathizers from conducting even more horrific terror acts in their name; in full or in part (Achille Lauro, Munich, Entebbe, 9-11, London Tube) - attaching to them forevermore the label: Terrorists.
What they need is a time-machine, to prevent themselves from gaining a reputation for saturating their childrens TV and radio programming and media with hatred and sugar-plum visions of godhead-rewarded martyrdom - repelling sane minds on the outside.
What they need are large tracts of arable, viable contiguous land, with access to water and waterways, trade routes, infrastructure, etc., rather than two disconnected and rapidly shrinking pockets of population; one of which (the West Bank) loses more ground every day, and which, itself, is already fragmented into scores of pockets within the older pocket.
What they need are leaders (and an electorate smart enough to put them into office) who accept the defeats of the past, who begin their work from that point moving forward, who swear-off the use of violence, who commit to peaceful co-existence, who concede Jerusalem, and who work towards dividing Old Palestine into two contiguous tracts of land; one for the Jews, one for the Muslims; both with access to water and resources and trade-routes and the like; like they should have done back in 1948.
What they need is the sanity to recognize the error of their ways (methods, etc.) and to commit to doing it differently, moving forward; convincing everyone (most importantly, the Israelis) that they mean what they say about a change-of-heart, and making it stick.
What the Palestinians need is a miracle.
Given their nature and their intransigence and political immaturity and foolishness, they will not get one.
