The idea that foreign countries can decide where Jews can and cannot build, then, is also often believed to run against one of the more fundamental pillars of Zionism, namely that Jews are finally independent and don't have to rely on whether the world has a favorable or an unfavorable opinion of us. This, of course, makes the U.N. and international law in general spectacularly unpopular, especially so because the U.N. is -- rightly, in my opinion -- perceived to ignore real injustices in the world.
The U.N.'s primary focus is order, not justice. That said, the idea that any country need not consider what other countries think of it strikes me as delusionally arrogant. It's an arrogance that can only be sustained so long as a country remains stronger than its neighbors. Israel will retain that advantage for some time, but not forever.
I suppose if I shared your messianic vision, I might also ignore the lessons of history. However, even if I did, I'd hardly expect others to do so. (I'm not even one of those Christians who see the need for a restoration of a Jewish State as part of Christian eschatology.)
