More Weapon = More Rights?

The power the Security Counsil poses:

-Investigate any situation threatening international peace;

-Recommend procedures for peaceful resolution of a dispute;

-Call upon other member nations to completely or partially interrupt economic relations as well as sea, air, postal, and radio communications, or to sever diplomatic relations;

and

-Enforce its decisions militarily, or by any means necessary.

Now that to me is a very powerfull council which can directly influence every state in the world. Giving the fact that there are 5 permanent Security Council seats:

The French Republic
The Republic of China
The Union of Soviet Socialist Republics
The United Kingdom of Great Britain and Northern Ireland
The United States of America

It would make any rational person wonder why this is, why these nations should have any more rights than any third-world nation? To me this is bizzare specially when:

In 2004, four of the five permanent members were also the world's top four weapons exporters when measured by arms value; China was seventh

This is rediculouse. These people are in charge of the world security because they have more guns, wow. Imagine if this type of ludacris ideas governed our streets. If you don't accept this within your nation than why do you accept it in broader terms.

If you don't accept imperialism than why accept this, shouldn't the world have a say to who should be in charge of our security?

VETO!! Do I need to say more?

protecting the oil-rich Kuwaitis in 1991 but poorly protecting resource-poor Rwandans in 1994.

This is injustice in global terms.
My question:
-Why do we allow this type of injustice to exist?

Very true, more weapons = more rights. It just gives nations the ability to do what ever the crap they want in name of interest. It has been like this since time. I think the point is that today people seem to think other wise, the seem to think empires don't exist, they seem to think colonies don't exist, they seem to think slavery don't exist. You have put it very nicely. People seem to think we are modern now, specially the west but we are as barbaric as ever with the same rules which ruled mankind since we can remember.
