You can't rely forever on your reputation of 50 years ago. Time to get with the programme. He said 'american weapons', and not necessarily that americans are using them. He also didn't say anything about americans liking killing children. If anything, we are too lenient towards them.
Some people consider teenagers or the mentally retarded to be children.
Those that consider Great Apes persons with some degree of rights would consider this murder. So I think it is a bit different. The United States led the world in executing persons for childhood offences. It was ahead of Iran, Nigeria, Pakistan, Saudi Arabia and Yemen combined. Greenpeace should work hard to expose the hypocrisy of the governments the big corporations in these G8 countries.
