"Well, there’s a kick in the teeth to all you red-blooded Americans
wearing your country’s uniform: It turns out non-Americans donning U.S.
military garb have more stick-to-itiveness than you, as well as having
vital skills the U.S. military needs that you don’t have, to boot. Non-citizens are “a potential source of language and cultural skills
that are of strategic importance to military operations outside of the
U.S.,” the new Pentagon report notes. Adds an earlier study
from the Center for Naval Analyses: “…relative to citizen recruits,
non-citizen recruits generally have a stronger attachment to serving the
United States, which they now consider to be `their country,’ and have a
better work ethic.”" - Time, Apr. 6, 2012.
