Sweden and Denmark would send troops if America signed an environmental treaty but thats tough.
Sweden wouldn't anyway, because we are obsessed in this country about the Iraq war being a crime against international law, something that's considered holy here.
If Kerry's elected he will undoubtedly improve the relations between America and Europe, and that's needed.
But I don't think it will lead to France and Germany sending troops. The leaders of these countries are cynical cowards. Perhaps Kerry can convince them to contribute money and train Iraqi policemen, though.
