The comment was about Greeks' stance towards Israel and Jews, not the U.S....
I think most countries--including the US--are largely anti-Semitic and anti-Israel.
In defense of one Greek though, my girlfriend's grandmother is Greek. She married into a Jewish family and has been nothing but nice to me and my girlfriend (we're both Jewish).
You have no clue about Greeks or those of Greek decent.
You can provide a loony supremacist anecdote of any group to any other group.
This is only a hollow statement on the surface which seems to carry a clear subtantive message between the lines. Attention: return the hostage or more "excessive force" will be used until the hostage is SAFELY returned.
