Since the days of Nimrod Nationalism has been the the order of the day - until WWI.   At the end of WWI the League Of Nations was formed to begin the process of Globalization of the world.   

Hitler's plans got in the way.   As a result, the League Of Nations fell apart.   

However, upon the end of WWII the League Of Nations was resurrected and rename the United Nations.   

The United Nations has picked the Globalization ball and rand with it.   

Over the past 20 years we have seen an attempt by the United Nations to pass laws superceding the laws of its individual states.   

As a side note, the United States has been the biggest promoter of and financier of the United Nations.   

As with all satanic ideas, there is a tantalizing flavor that induces his victims to little-by-little fall into deception and destruction.   

It sounds like a good idea to unite all nations, doesn't it?   

But anyone with any experience of trying to unite a bunch of disparate people knows that it is impossible to do so without all the people dropping their own ideas to accept the idea of one person.   

So, in the process of uniting there is a casting away of principles and values.   

When we look at the stark failures of socialism/communism experiments we are left with the realization that success and prosperity are not guaranteed by unity.   As a matter of fact failure is guaranteed by unity based on wrong-thinking.   

That is where Nationalism comes in.   Because there is no single 1 idea being forced into play, one nation may choose a path of failure (such as has been the case with USSR, Venezuala, Cuba, etc).   while other nations who choose other paths are prosperous.   

Don't put all your eggs in one basket.
