"The trouble is that nail was removed from the shaky supports holding up what's left of our constitutional republic."
I didnt realize our constitutional republic depended on us not having a single point of contact and leadership on terrorism and intelligence... where did you get that nutty idea? ... you think our rights are more secure with an inefficient, sprawling, multi-headed and compartmentalized organization facing new terror threats?
whatever the case, it's not something in the Constitution one way or another ... except that "Provide for the Common Defense" bit, which I think covers all of this.
I regard any major concentration of government power with concern.
