Osama bin Hitler?

The comparisons of Osama Bin Laden to Hitler seem to me a bit tenuous.  Other than they were both obviously assholes, their results are the complete opposite: Hitler was responsible for tens of millions of deaths and a war that propelled the USA into it's role of world superpower with decades of hyper-productivity and economic upswing; Osama killed 3,000 people on a single morning that propelled us into at least a decade of total economic collapse and a complete willingness to forfiet those things that make us "American," e.g. civil liberties and a high moral standing throughout the world.  We should all be happy he's gone, but was the price worth it?  While nobody would consider such a question with Hitler, it seems a very plausible one to me.
