Much of their analysis strikes us as solid -- but the rebellion is problematic nonetheless. It threatens the essential democratic principle of military subordination to civilian control -- the more so because a couple of the officers claim they are speaking for some still on active duty.

If they are successful in forcing Mr. Rumsfeld's resignation, they will set an ugly precedent. Will future defense secretaries have to worry about potential rebellions by their brass, and will they start to choose commanders according to calculations of political loyalty?

At the same time, David Broder says:

Seeing these senior officers take this public stand is unprecedented; even in Vietnam, with all the misgivings among the fighting men, we saw no such open defiance.

Rumsfeld and President Bush insist that the manpower and strategy have been exactly what the commanders in the field thought best, but now general after general is speaking out to challenge that claim. The situation cries out for serious congressional oversight and examination; hearings are needed as soon as Congress returns. These charges have to be answered convincingly -- or Rumsfeld has to go.
