What is the location of the jungle Frankie is running through?  Answer the above question based on the context below:  The film begins with stock footage scenes of warfare in Vietnam. An American soldier named Frankie is seen running alone through the jungle as his voice narrates. He explains that he "goes back there every night" right before he wakes up in bed with his wife in their squalid NYC apartment. The distorted cries of his baby are heard, and his pregnant wife wakes up to tend to the boy. They argue over Frankie's unemployment and their son's health. The baby is a mutant, which Frankie assumes was a result of chemical weapons used during the war. A junkie scores from the local kingpin, Paco. Frankie waits in line outside the unemployment office. The junkie desperately searches for a needle to shoot up with. Frankie kills time entertaining a child prostitute. The junkie resorts to dumping the drugs directly onto a wound he opens in his arm and passes out. A random woman comes upon him and steals his gun and ammunition, putting them in her purse. There is no work for Frankie at the unemployment office. Unexplained arbitrary things happen, such as one social worker asking another if he's seen his Veg-O-Matic. Frankie's social worker spaces out during their meeting and says, "Life is hot, and because life is hot, I must take off my jacket." He then resumes the meeting, imploring Frankie to go back to school because he has no marketable skills. Frankie is desperate for work, having been unemployed for four months. He calls his father to ask for money. His father thinks the call is a prank, since he believes his son died in Saigon. Frankie explains that he was reported killed 15 years ago but made it out alive and spent three years in an army hospital recuperating. He tells his father that his wife is pregnant again and they are being evicted, but his father claims that he is also broke and about to die from a heart condition.
The answer to this question is:
Vietnam
