In the first picture the reader can see a graffiti on a wall of a building. You can see two different parts, the first part there is a man wearing a red suit like the prisoners in guantanamo. The second part are just 7 words"occupy land...steal oil...the american dream". The drawer wants to criticizes the US politic because he thinks that america invented in Iraq because of the oil and not to bring the "American Dream" which means wealth and pursuit of happiness to these countries.

In the second picture you can see George Bush sitting in a wheelchair. He has a pistol directed to his head to commit suicide. The word "sorry: is drawn over his head. The author of the graffiti tries to show the people how George Bush should feel about his act when he was the president of the US. Because of his acting the economy is down and an America were losing many soldiers in Iraq. 

Both graffitis are very critical with the US government, specially the Bush administration.
