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.
