New World order ?

3 Things to consider:
1st: Human nature makes it impossible to create such a new world order.
Even the old world order didn't work well because of the human nature, but most societies have found ways to work well despite the human weakness.

2nd: A revolution is no Kinder garden-Carnival, it's blood on the streets and shooting "enemies of the people". It's not uncommon to shoot the first members of any revolution later because "they secretly have worked together with the enemies of the people".

3rd: Any revolution ends with a new government... and because this government was created by bloodshed and a change of human nature is impossible the same problems what have lead to the revolution will cause sooner or later new bloodshed.

And talking about gun's and politicians...
Everyone is a politician. If you visit the town hall because there is a discussion about to build a new road near your house... how did a gun help you here - shoot everyone who isn't your opinion because he is a part of the new world order ?
At the basic level politics are simple, but not all problems can be solved at a basic level.

There is a thing called basic consensus what keeps every society together. One of this basics is to accept a legal desiccation even it's negative for the own interests.
Any society there many members quit this consensus will break, causing sooner or later a civil war.

And the civil war will be fight along the lines of personal believes. It's quite possible what in your 2nd American revolution you must shoot at people who don't belive in the existence of a "new world order".
People who may haven been your friends, your class mates or your relatives (maybe your own brother)...
And after your revolution you must oppress them, because they have fight for the other side...
Are you ready to do this ?

Translated statments of AlKaida and the RAF are aviable on different sites of the web, have a look on them and ask yourself if you still want to go this way...
