You should not confuse the ability to contemplate to be the same as brilliance, indeed the lack of hesitation to contemplate the absurd or unacceptable is the opposite of brilliant.
For example, the pros of killing everyone over the age of 75 could take hours to fully contemplate, the spread sheets could be masterfully done, the deep intricacies of how it could send a financial spider web of benefits throughout the economy could take years to fully understand. And yet, I find those that dismiss the thought within seconds to be the truly brilliant ones.

Your analogy on 75+ is extreme, and I'm sure Pat would nix it in a nano second. Strategies in dealing with barbarians, stick or carrot, is quite another thing.
