Spengler observes that "The West will attack Iran, but only when such an attack will do the least good and the most harm."
I worked for a CEO who knew that he would have to fire a goodly number of employees because of a funding cut. And everyone in the company knew it, as well. By acting quickly in response to the funding cut, the CEO could have reduced the number of firings and relieved the minds of those who worried needlessly that they would be fired. But the CEO couldn't bring himself to act quickly, and so he put off the firings for several months. The result: more employees fired, a prolonged period of reduced productivity during the months of delay, and a less functional company after the firings (because the firings disproportionately affected the support staff).
Delaying the inevitable usually makes matters worse.
