Beware: the Greeks are viciously anti-American, even before the Iraq war. (Not Greek-Americans though.) Not sure why: perhaps a combination of the traditional Greek-Arab friendship (both were ruled by the Turks) and because left-leaning Greeks are WAY left and have never forgiven us for the pre-democratic regime of "the Colonels" (1967-74) which they are sure were all CIA agents.
