What are the main responses to the military activity in Iraq that are represented by the people Robin is describing in this quote?

Explanation:

Walter Dean Myers’s stunning Coretta Scott King Award-winning novel, Fallen Angels, about the Vietnam War, was published in 1988. Twenty years later, Walter has written a riveting contemporary companion, Sunrise Over Fallujah, that again shows the devastating personal realities of war.

In Fallen Angels we met 17-year-old Richie Perry, a soldier in the Vietnam War. Now, in Sunrise Over Fallujah, set in 2003, Walter introduces us to Robin “Birdy” Perry, Richie’s nephew, a kid from Harlem, who comes face to face with war’s ugliest sides - and recounts this in letters to his Uncle Richie. Through Robin’s account, we begin to understand the realities behind the headlines - about the horror of war, and what war means to young people and their families.
