A Question about Palestinian Statehood

(This is only indirectly related to metaphysical naturalism and theism, so please forgive me if this seems too off-topic for you.)

In light of the recent decision about the UN’s decision to recognize Palestine as a Non-Member Observer State and the opposition to that status by the U.S., Israel, and others, I have a simple question.

If North Korea gets to be recognized as a full member of the UN, then what objective basis is there for excluding Palestine? Most of the international community opposes the policies and actions of North Korea, but I’m not aware of anyone suggesting that North Korea should be stripped of its UN membership. Why should Palestine be treated differently?
