You are right, and awhile back there was a somewhat more extensive article posted on this. I can only think that the terms “commissars” and “ministers” sound too real - people would sit up and take notice of them. But in America, the term "czar" is a faintly comic term. No one really believes we have actual Soviet-style bureaucrats here, and so the term is more easily taken lightly, or dismissed as hyperbole.
Which is, of course, exactly the public reaction that the commissars want.
It does have a kind of comic opera ring to it. Like they are all wearing plumed hats and lots of gold braid. (I have a mental image of Gen. McCaffrey, when he commanded SOUTHCOM, with lots of decorations and gold braid, but thankfully no plumed hat, who was later Clinton’s drug czar.) I guess what bugs me is that the Czars were absolute rulers, autocrats, and these guys are merely the tools of Obama’s trade. And that’s not funny at all.
