Amnesty Unconstitutional

According to the Washington Times, a federal judge has declared Pres. Obama's Executive Order on amnesty as unconstitutional.
Sounds like the system is working, but is it?. The Obama Administration will next follow the standard procedure of appeal to a Circuit Court of Appeals, and if that decision is not favorable, Obama will carry it to the Supreme Court.
Let's assume that the Circuit Court of Appeals sides with the federal judge and declares Obama's amnesty as unconstitutional. Similarly, let's assume that the Supreme Court comes to the same conclusion. Then what? Nothing. Do you really think it'll Obama is going to change his amnesty program because of what anybody else in the federal system says. I'll bet a hat he will not.
Does that mean we are dead in our tracks on amnesty? Not exactly. The Congress can impeach Pres. Obama and also discharge him from office. Will he go? Not likely. Remember, he is Commander-In-Chief of the military, so that he has force of arms. Will the military support him? Soldiers have been trained to follow orders of generals, including the commander-in-chief.
Maybe it's a good thing that there has been a significant increase in public gun sales. I'd hate to see a civil war to depose a president/dictator, but if necessary to save our country, so be it
