Actually, Yes they can.
And they have expelled countries before. China was one of them after World War II, I believe. I am not sure if Germany walked or was expelled but there was a short period of time when they were not part of the UN because of Hitler. There have been threats towards countries of expulsion towards countries as a means of keeping them in line.
Expulsion from the UN means no aid and cease in trade which can seriously damage many nations. For instance... the larger part of China's income comes from their trade with America. Hence the reason we have so many Chinese products. If China is expelled from the UN, then the US would have to with drawl their trade with China in which will cripple their economy and in turn cause an economical disaster for them. This keeps most countries from going to war with one another or violating the UN's principles.
You are right though, the UN was ORIGINALLY created as a peace keeping organization... however, over time they have gain more and more power over nations. Some say that in time the UN may take over as a centralized global government that will create a world wide governmental system similar to the system in the US. Only time will tell if this will happen and if it will be a good or bad thing. Personally, I would actually love to see the world unified under one government and one set of laws. It would eliminate a lot of wars that way, but only if that government is just and true.
United Nations Charter said:A Member of the United Nations which has persistently violated the Principles contained in the present Charter may be expelled from the Organization by the General Assembly upon the recommendation of the Security Council.
