No, it's wrong to use UN as a political tool, because that's what most of resolutions against Israel are.
Very simple explanation and history insight - USA and USSR supported creation of Israel, both wanting to have it chose their side. Well, surprise surprise, Israel chose the West. And thus you have the islamic block (duh...), the countries dependant on the oil said block provided and still provides, plus USSR with it's satellites and influenced 3rd world nations = tens of resolutions against a single country. A democratic country, even.
Obviously not a lot changed after the fall of USSR.
