Discussing motivation is difficult. You usually can’t prove it, so when you assert a nefarious motivation, the discussion turns to how can you be so mean to that nice Mr. Obama who only wants the good. It obscures the discussion of the actual action–generally on purpose. And it discredits the asserter.
OTOH, the issue is that if we correctly discern the motivation, we may be able to figure out what the next step will be if the motivation is as we presume. Could be possible to be prepared.
And on the other other hand, you have to wonder if incompetence is sufficient. Yes, somebody might be stupid as hell, but isn’t there a maximum to the stupid effect that is less than some possible actions which go further? If so, we need another motivation.
