Where is the condemnation of the US "dirty weapons"?

This is the real world we live in now!! The more powerful you are, the more people listen to you and you can convince them. The only country that ever used WMD was USA and the only country who got the right to allow anyone to have them or not is USA. US is the biggest dictatorship on earth. The world is full of hypocrisy, there is nothing called democracy..all big theatre!
