It failed to bring most of the wars (or "police actions") into the picture. Maybe because all of the 'major' conflicts prior to desert storm (C/WW1/2/K/V) were headed by the opposite political party than that mentioned. This is not to say other conflicts didn't happen under other parties as they obviously have.
While the reasoning is sound insofar as the 'unmentioned' conflicts were fought primarily by draftees (again - politics?), it really gives no satisfactory reason, only conjecture and opinion (politics) on the current military actions - which SPANS political parties.
Sadly, the introduction of politics into an article initially put forth as something about the "morality or war" says more about the intent of the author than the question the article brings up.
