Pretty damn stupid remark. Of course it is not possible to arm the opposition enough for it to militarily defeat the regime, which had spent decades arming itself against Israel, the dominant military power of the region.

Even "other ranks" are not automatons and an army can disintegrate remarkably rapidly if the soldiers lose their respect for (or fear of) of their "leaders."
