Palestine is a recognized state

I’m sure the David Frum, Jon Podhoretz, and other advocates of open immigration will be eager to defend the right of the world’s newest nationals to freely immigrate to Jerusalem now:

PA Chairman Mahmoud Abbas Sunday promised someday the PA flag would
fly over “Jerusalem, eternal capital of the state of Palestine.” Thousands of people greeted Abbas rapturously upon his return from
the United Nations, where the General Assembly granted the PLO,
representing the PA, upgraded status as a nonmember observer state.

It seems strange that so many people are obtaining the right to self-determination around the world, with US support, with the noticeable exception of Americans.
