According to the BBC, even Switzerland has expressing a view on the war:

Switzerland banned all military exports to countries engaged in the war against Iraq. A spokesman said it would break the country’s neutrality rules to do so, because the war had not been sanctioned by the UN.</p> In fact, Switzerland has maintained its neutrality, but the export ban is very real.

Exports of Swiss military material amounted to $216 million last year, with the United States and Britain were among the top five importers.

Swiss president Pascal Couchepin said he “regretted” the military action against Iraq and also announced that his country was banning military, surveillance and reconnaissance flights over its airspace by the United States and its coalition.
