The Catholic Church has always been international in it's outlook. It's historic support for the UN is in keeping with it's commitment to peace. The UN is imperfect like all human institutions and the Church has fought hard to influence it where it could.
It's interesting that you take this position because I think it is revealing. It exposes the different mindset between Rome and the extreme traditionalists. Where Rome is willing to get it's hands dirty, working with the sinners of the world, associating with the sinners of the world, and confessing that it's members are sinners too, the extremist's seem to propose a more isolated approach. The extremist's would disavow themselves from anything that reeked of iniquity, including, and especially the Church of Rome that passed to them their faith. They would prefer to be untainted by the world the Lord has placed them in. I think that interesting, and definitely something Jesus had something to say about.
If the Pope thinks this, it's no wonder he sided with Saddam's buddies recently.
And you deny calumny?
