The Constitution (granting powers/authority to a centralized government) was written so that our freedoms could be defended.
I don't think you and I disagree on these issues. I'm assuming we both think that central governmental authority should mostly be limited to the preservation of our liberty (the "securing of those rights). Yes, that includes national defense and neutralizing Islamic terror.
I'd like you to convince me that Rudy doesn't disagree either, that he really understands and cares about our founding ideals, but convince me in some other way than trying to justify his statements in this speech. Because I think those 2 sentences of his were either boneheaded or wrong headed.
I don't think we had a president in nearly 100 years who believed in our founding ideals, except for Ronald Reagan, so if Rudy understands them, that makes him a major exception.
