There's a small group of people in the world today, almost entirely American, who have made something of a sport trying to tie current world events into the book of Revelation. Often, their reasoning is quite dubious - a beast with ten horns? Clearly a one world government with ten regions!1
One of the favorite targets of these prognosticators is the United Nations. The UN is a world spanning power (never mind that it's powerless) and that looks kind of like a on world government, which we all know will be the government of the anti-Christ (see above). And, they like to point out, the UN wants to split the world into ten governmental regions (something I've never been able to confirm outside of their circles) and the Bible talks about a beast with ten horns that is so clearly a one world government with ten regions, the connections couldn't be more clear (ten being a very uncommon number and all).
That isn't to say I'm a fan of a one world government or anything. Often, entities that seek one world government are grasping and imperialistic (Ancient Rome, Hilter's Germany, etc.) and, even where they aren't, they would set up an inefficient, centralized system of government, which you all know I'm no fan of.
Heck, the UN is a far from perfect institution. Mostly powerless, where it does exert influence it often does more harm than good (look at affiliate organizations like the World Bank) but all this has nothing to do with poverty.
But the UN is no one world government, it's not even close, and even if it were, their reading of Revelation is dubious to begin with.
What the UN does do is tell countries (mostly ineffectively) what to do. Countries like the United States.
And that's the real reason they hate and fear the UN, because it has the presumption to tell the United States of America (God's Country after all!) what to do.2
1. Actually, since at least some of the point of Revelation (I think) is to prophesy historical patterns (as opposed to specific historical events) they can even be right, but not for the reasons they think.
2. I should say I don't think most people who follow these "interpreters" of Revelation have this view, I solely blame the "interpreters." I doubt even they are quite aware of it. This is simply a symptom of patriotism meaning more than faith in God.
