Quite right sir (or madam).
leaving aside all the braying about crap Dell machines, US Imperialism, Michael Dell's political affiliations, etc., etc., this has nothing to do with any of these.
The United States is a signatory to the Wassenaar Agreement. This is a multilateral agreement on export controls for conventional arms and dual-use goods and technologies. Signatory countries are: Argentina, Australia, Austria, Belgium, Bulgaria, Canada, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Japan, Latvia, Lithuania, Luxembourg, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Republic of Korea, Romania, Russian Federation, Slovakia, Slovenia, South Africa, Spain, Sweden, Switzerland, Turkey, Ukraine, United Kingdom and United States. (Israel didn't sign it but agreed to abide by it.)
So, if your country's on the list then it, too, may be an imperialist tool with industrialists who are in the pocket of right-wing politicians and who make crap computing equipment. Or, alternatively, we could always do a little learning before running off at the mouth on El Reg.
