My concern is more Bannon at the head of the Military. The military is a bunch of serious motherfuckers who have vowed an oath to defend the constitution above all. They also strictly follow the command structure. Which now has them reporting to Bannon, and him to Trump. So they issue a blatantly unconstitutional order to block all immigrants at the border, and the DHS (aka: TSA) holds legal Green Card holders at the airport. THIS is the practical aspect that worries me. Trump says something dipshit loony, and the guys with the guns and no training jump to fulfill his orders without the honor, respect, training, or skills of the military. Nobody at the DHS said, "Ignore that order, because it is stupid and unconstitutional, and has no practical methodology for implementation." THIS is our concern, dude.
'member back when McNamara decided we needed "launch codes" in order to start a nuclear war and Curtis LeMay had them set to all zeroes because no pencil-neck actuarial geek was going to tell him who he got to bomb? It's not that he didn't take the job seriously. It's that he took the job more seriously than Robert McNamara. Bannon had the Joint Chiefs removed from the National Security Council. The military reports to the Joint Chiefs, not to Bannon. The Executive has JSOC - which is probably why we ran a dunderheaded SEAL Team Six raid into Yemen that involved 30 dead civilians, two injured pilots, a scuttled V-22 and a dead SEAL. The guys that popped bin Laden without so much as a scratch and we're pantomiming Carter's hostage rescue. Clearly, they're playing whatever GI Joe games they can. But the conventional military structure? I mean, we didn't even go play saber-rattling games in the Gulf or anything. We're talking about hair-on-fire constitutional crisis over one religion, seven countries. We're talking about guys at the DHS saying "follow that order, because stupid and unconstitutional as it is, it was given to us via a constitutionally sound process and until this shit gets sorted out, we gotta do the thing." I can see the argument that it is of a kind with the New World Order marching on California but in much the same way that budgies and velociraptors are of a kind.
