Ah but it DOES matter what country is selling what to whom. People from many countries, including Germany, are CONSTANTLY beating the drums about how it's all the AMERICANS' doing because the EEEEEEVEEEEEEL AMERICANS sold all the weapons in the first place, and helped aided some defunct regime in (enemy here), usually DECADES ago, so WLL THE PROBLEMS OF THE WORD ARE AMERICA'S FAULT.
When the shoe winds up on the foot of one of these 'morally superior' countries, particularly ones which WOULDN'T EVEN EXIST WITHOUT AMERICAN MILITARY INTERVENTION, most of us will be d@mned quick on the payback trigger.
