In the recent history we have not heard of any country invading another country with almost global and UN approval, except USA, simply because it is capable of doing so due to its Military & Nuclear power.USA does not want any other country to attain that position.
USA invaded Iraq to seek and neutralise WMD. it did not find any such thing. Noe id the world's political community has any regards for human life,self esteem and fairplay, they should collectively call for trying George Bush under War Crimes.
