I hate to pick nits, but I think Sweden is a neutral country. They wouldnt have sent troops anyway. I could be wrong though..
Sweden, like Switzerland, is a supposedly neutral county. During World War II, they were happy to sell Hitler iron ore for his war machine while Switzerland was happy to guard his gold extracted from the teeth of murdered Jews in nazi concentration camps. This neutrality makes them morally superior to us cowboy Americans. </ sarcasm>
The article failed to mention that the Swedes didn't send troops to WWI or WWII, the Korean War or Viet Nam. I don't think we lost any sleep wondering if Sweden was going to join the Coalition of the Willing. Denmark did. I think if Sweden were invaded, they would declare neutrality.
