They die for other's freedom. However, they need to stop picking fights with whoever the forget they want too. Vietnam made sense, as South Vietnam didn't stand a chance (and now SV does not exist), however, the generals were dumbasses. The USA probably could have won if we had stopped richarding around.
Afghanistan... how the forget will the USA win? Why did we go in there? The guys on top are always the issue, not the grunts getting shot at.
