Likewise your other thin comparisons. They lack a certain depth that cause them to ring of disingenuousness. For instance, our actions in the past at least attempted to provide some pretext of military aggression against the U.S. or its allies. You yourself called them "interventions". But, you could not call Iraq an intervention, as there was no military pretext. It was unprecedented because we didn't even attempt to trump up the military pretext. We simply went to war based on what they "might do". Your attempt to dismiss such an obvious departure from American doctrine speaks for itself. In fact, it's so obvious that I actually feel silly responding.
I also wrote Bush's adherence to the strong unitary executive principle, which acknowledges its pre-existence. It was his extensive application of the principle that represented the power grab, per the examples I gave. Much of my comment was about the expansion of existing power vs. the "raw creation" of it.
In general, your citing examples of past abuses are just straw men. I never said that the U.S. has a perfect record or that there has never been abuse of power. But, we are living in a time wherein the Executive has more accepted power than in the history of our nation, and much of it has been enshrined into law. Again, the PATRIOT Act alone is unprecedented in the degree and scope of rights and protections that are given over to the Executive.
To ignore these realities and attempt to rationalize this power grab by spurious comparisons to the past is, at best, non-serious.
