US has a history of committing genocide...it even tested nuclear and chemical weapons against their own populace in the 50's and 60's..

of course we know about the american mass murder of the civilians in japan after dropping 2 nuclear weapons over two cities..

we have the vietnam war...lots of chemical weapons used over wide areas and many thousands of civilians were killed

US and her allies carpet bombed berlin during the second world war...many thousands were killed...

america was involved in the Korean wars..

we have had the wars in Iraq and Afghanistan...again thousands of civilians were killed...

we could carry on but i think i made my point...
