How about nukes for all!

US intelligence confirms. And the latest news is that Brazil is on the verge of having a bomb. Now the question is if America allows Pakistan, a sensitive country in many respects and the world is at a very crucial juncture; than how about all the countries in the world having the same nukes? The logic behind my point is if all these countries possess the same dangerous weapon, none of them would dare threaten others! The point gets logical if you observe the case between the most hostile countries in South Asia. They fought three wars when they didn't have any nuclear weapon. But there has been no war since India and Pakistan built their nuclear arsenals. So if the countries across the world possess the same power there will be no more war. It's like the American cowboy culture!
