Let's be clear about this. Most Americans don't want their government to be the world's policeman. They think their government sticks it's nose where it doesn't belong at the cost of American lives and resources. Most American soldiers think their government gets involved where it shouldn't.
Americans support their soldiers. Soldiers do what their government tells them to whether or not they agree. The ugly truth is that American big business controls our elected officials in the Congress. American corporations like Northrup and General Electric make huge profits from war. Many energy companies are vested into foreign oil. They spend tremendous amounts of money on lobby groups which find ways to funnel it to our elected officials to buy votes. Big money tells the government what to do. The majority of Americans stand like deer in the headlights, shocked at what idiots our elected officials are.
The government doesn't like Americans to see the photos shown because it stirs resentment. The government prefers Americans to be stupid and complacent.
