Only against an occupier unwilling to meet it with measures harsh enough to be effective. Historically speaking, I'd say it is more likely for US military forces to employ such measures against Americans, than against occupied foreign polities; as far as I can think of, we've actually never done the latter, while US history exhibits at least two instances of the former -- the Indian relocation, on the one hand, demonstrating the effectiveness of mass resettlement, and Sherman's March to the Sea, on the other, doing likewise for "scorched earth" techniques and reprisal killings of civilian hostages in response to guerrilla attacks.
