This is probably the most difficult question that I’ve received. I’m not an expert on the legal issues, I’m not an expert on defense issues, and I don’t even have any strong gut instincts.
On the pro side, I suspect the world is a better place every time a drone wipes out a nest of terrorists. And that’s true even when the casualties include traitorous Americans.
On the anti side, every good libertarian worries about the slippery slope of government expansion. So even though I’m somewhat happy about terrorists getting zapped today, I don’t like to think about who might be targeted by politicians 30 years from now.
Part of the problem is that governments grab additional powers during wartime, and it’s very difficult to unwind those powers once hostilities cease.
And to make matters more challenging, we’re now fighting a war that presumably will never end.
Yes, we can probably ameliorate the problem by reducing American interventionism, but I strongly suspect that radical Islamists also hate us because of our tolerant values and secular system. So we’ll still face a serious threat of terrorist attacks even with a perfect libertarian foreign policy.
I guess the only answer I can provide is that I want plenty of independent judicial oversight. No, that’s not a panacea, but it’s at least some form of check and balance on the executive branch.
