...country that poses the greatest threat to U.S. security may be neither of those where American boots are on the ground. Beset by feckless leadership, preoccupied with its rivalry with India and infested with militant groups, Pakistan in 2009 became a viper pit of terrorist plots and political malaise. The death of Taliban leader Baitullah Mehsud in an August drone strike ratcheted up the stakes. After months of planning, Pakistan's Operation Path to Deliverance sent 28,000 troops to root out insurgents in South Waziristan in October.

Stamping out a few butts could amount to very little in comparison...
...reason is less air time, researchers say - the less time a runner's feet spend airborne, the less force they strike the ground with. Still, the results of a mathematical model are difficult to re-create in real life, especially since it takes a fair amount of practice to adjust to a shortened stride. Runners who abbreviate their stride try instinctively to quicken their pace to compensate. That can negate any protective effect of stride shortening - when you speed up, the force on the bone increases proportionately...
