In my humble opinion, the Swedes, a nation so snotty and uppity they could not see further than the end of their own noses, got their asses kicked pretty badly. Pride comes before a fall I guess :p

On a side note, they were outnumbered and had the misfortune of being led by an idiot at the battle of Poltava.

Dude, your right that they were prideful and that eventually caused their defeat. But the Caroleans(Swedish Soldiers) were rightfully so. Body for Body they were the best soldiers in the world at the time. Heard of the http://en.wikipedia.org/wiki/Battle_of_Narva_(1700). 8000 Swedes defeat 40000 Russians. Or
the http://en.wikipedia.org/wiki/Battle_of_Holowczyn. In the first part of the war it was the Swedes doing the ass-kicking. Charles XII was a brilliant commander who made a terrible decision. Caroleans had defeated the slavs before at similar numbers but Poltava they just couldn't repeat the feat.
