Not at any cost, no. Now what with all of the "America...fuck yeah!" rhetoric after Bin Laden was killed, I gather that I might be writing for the minority opinion.
How many kids will die because they now won't be getting polio vaccines? How does that number compare to the number killed at the World Trade Center? If the numbers are comparable, then we figure brown kids have less value than Wall Street bankers? So, maybe apply a value of two-thirds (I'm pulling numbers that have been used in the past) one brown kid for someone working in NYC? If not, then what's the math that we can agree on?
It was all just a revenge killing anyway. Are we now safer with Bin Laden dead? I'm open to opposing opinions, but as far as I can tell we haven't improved anything.
