People often confuse responding appropriately to challenges, which is always good, with the idea of defending an existing position, which is often bad. When we focus on shoring up defenses--lots of examples during the course of political and sports contests--we often lose sight of the key elements of the situation. Often the situation is that we are in a position that we shouldn't have gotten into in the first place and the best response is getting out of it. While all we can do is defend when we don't have resources to advance, the process of picking a defensible position is part of the progress cycle (the aim step), which should make defense of an existing position (even field positions, which are transitory) easy and affordable. Responding to situations appropriately is a type of defense, but it is not the same as defending a position. The issue of response is to avoid getting out-maneuvered, that is, being put into an indefensible position by the dynamics of the situation. Defense of a strong position is virtually effortless. Defense of an untenable position in worse than worthless.
