the only viable path towards enforceable palestinian rights law is as full citizens in an israeli state. any theoretical palestinian state, as unlikely as one ever is, would be another backwards theocracy that oppresses it's own citizens, and where people have no civil and legal rights to deviate from violently enforced religious norms. it would be another brutal dictatorship in the region, and gaza under hamas is the inescapable model for it.
refusing to allow israeli annexation of the west bank continues to indefinitely and endlessly render the palestinian people as stateless and rightless until they simply cease to exist at all, which is the inevitable outcome of the status quo, and leaves them with no democratic influence into the events unfolding around them.
if you are opposing annexation out of concerns about what israel calls a "demographic problem", you at least have a position rooted in logic, but it's fundamentally incompatible with the values of secular democracy and a position i would strongly oppose. if you are opposing annexation because you worry about the possibility of palestinian extremism destabilizing the region, which is the position held by local governments, you are in truth probably right. but if you think that opposing annexation of the west bank by israel advances the rights of the stateless individuals living there, most of whom are hebrew in ancestry, you are an absolute idiot.
19th century european ethnic nationalism is a foolish model to colonially enforce on 21st century populations on the periphery of european civilization. in the modern world, states have diverse populations that speak multiple languages.
