Two points: (1) I don't think the people of Europe need to worry too much about the "riots" in Gothenberg. There's always a crowd of yobs who delight in joining into any passing trouble and with the internet now it is a marvellous opportunity to plan disruption. (2) Most history regarding Napoleon is looked at from the British side. Try the Irish side for a change. Suppose Napoleon had succeeeded in conquering and holding on to Europe? No Irish Famine? No Franco-Prusssian War? I could go on.
