My definition is no more vague than “policing the world”, which was in your original question. That means little to me, so yes, it’s hard to debate.
Well....then I’ll concede I was wrong in characterizing your position. Now....what exactly is your position? Let’s take it as a given that you support “national security.” Can you go beyond that? For example, do you think our support of the Jihadists in Afghanistan and Saddamists in Iraq during the 1980s was a proper policy or that it led to blowback? Do you think our installation of the Shah was a good thing or that it led to blowback? Do you believe our massive aid to Israel and Eqypt since the Camp David Policy was a good thing? Let’s get specific. Deal?
