@stratagos, allow me:
"Expecting nations to toe the party line when they don't percieve it to be in their interest is idiotic - or do you think the US should follow the consensus of Europe on issues?"
There is a very large (and productive!) grey area in between this extreme - defining one's national interest in the most narrow sense of the word, disregarding the opinion of powerful allies around you - and to "toe the party line".
It is precisely in this grey area that democracies should be operating, particularly given the context of the many international organisations they find themselves in.
The United Nations recently published a very nuanced, balanced report that stated that although the naval blockade of the Gaza strip (remind you of a good-looking former American president perhaps? ;) ) was legal, the violence used to enforce the debate was excessive.
This prompted Erdogan to change Turkey's fighter jets recognition system to report Israeli fighters as "enemy planes" and a very aggressive rhetoric against Israel. As the Dutch columnist Afshin Ellian pointed out: Mr. Erdogan is not at all the kind of man who's interested in balanced reports...
That's very characteristic of the world order falling apart: countries simply taking a nationalist or regional stance on an issue, without considering the sensitivities of their allies.
So to answer your question: do I think the US should follow the European consensus? Absolutely not. Do I think the US should be sensitive to the European consensus, because we're connected in many organisations and for a large part by ideology and factor it into their decision? Absolutely.
By the way, by building more and more houses in disputed territory, Israel is also embarassing the US, so I guess the two actions cancel out. And you can see the result: a completely pointless conflict between two countries that used to have good relationships, possibly involving NATO one day.
This insensitivity is not the way to go when you're working in an international context, and characteristic of a world order that is -unfortunately- showing signs of strain.
Does that answer your question?

PS: what's also a pity is that it often takes more generations to build peace, than to create conflicts. Sensitivity to history is another good property of the diplomat.
