Dont you Americans ever wonder why there are many Muslims that wish to harm American and US allied citizens.,,,,,,,,,,,,,,,perhaps it is cos the USA and her closest allies have invaded so many Muslim countries across the world, murdered millions of muslim citizens during the past 50 odd years.............and why does the USA do this with impunity............cos they can, you have started 210 wars and conflicts since 1945  and murdered 10s of millions, and at this moment in time you have military in 182 countries
