"Not all the Americans in Iraq are those who torture and murder, or course they're not, I don't know how many are doing it, I know it is systematic throughout the United States military I think that's been revealed"

John Pilger's quote addresses the intricacies and ethical challenges related to the U.S. military presence in Iraq. In this passage, Pilger acknowledges a vital distinction between private actions and systemic concerns within a military framework.

At first, Pilger makes it clear that not all Americans in Iraq are involved in abuse and murder, thereby recognizing that there are people within the armed force who do not engage in such activities and may even oppose them. This serves to humanize and protect those who are fulfilling their duties legally and morally, acknowledging their professionalism and commitment amidst a war-torn environment.

However, Pilger then raises a significant concern about systemic behavior within the U.S. military. By suggesting that he believes unethical practices are "systematic throughout the United States military", Pilger indicates that these actions are not separated occurrences however rather part of a wider, institutionalized issue. This assertion is effective and contentious, as it recommends an established culture or a pattern of behavior that may be approved or neglected by greater authorities.

The phrase "I think that's been exposed" shows that Pilger believes there is proof or trustworthy reports proving his claims. This likely describes various reports and investigations that have actually highlighted circumstances of detainee abuse and other misbehavior by military workers throughout the Iraq War, such as the infamous Abu Ghraib scandal.

Overall, Pilger's quote requires a critical examination of military practices, accountability, and the chain of command. It requires a nuanced understanding of the individuals within the military, separate from institutional actions deemed dishonest or illegal. Ultimately, it underscores the value of openness, oversight, and reform to prevent such practices and support ethical and ethical requirements within military operations.
