Not much of an argument, is it? This could be an argument against all German and Japanese products and even Italian products (maybe you do boycott all those).
Furthermore, should we refuse to buy IBM because they sold the punch cards to the German government that helped them organise the holocaust?
BTW, I have read that the Japanese did the Americans (and the rest of the 'west') a great favour at Pearl Harbor because it a convinced Americans to join the war and destroyed what was a rather outdated fleet of ships, thus forcing the US govt to build a much more modern fleet...
