I find the debate they’re having somewhat confused. Your response to Kling is on the right track, but I would question the terms of the debate from the outset.
The relevant question is whether US intervention produces armed resistance, and whether that resistance counts as blowback. It does, on both counts. Whether that resistance/blowback counts as “terrorism” by some narrow definition is really beside the point. And whether the resistance is morally justified is yet another issue altogether.
Kling mentions US intervention in Latin America and claims that there’s been no “terrorism” in response. How would he characterize the Cuban-Soviet precipitation of the Cuban Missile Crisis, which was a response to the Bay of Pigs invasion? Soviet positioning of nuclear weapons system was meant to strike fear in us (and did). “Fear” is a synonym for “terror.” The Cuban-Soviet policy was a response to our intervention. That’s blowback.
Re Asia, you’re right to adduce the Saigon counterexample you come up with, but that understates the relevant point. The relevant point is that the whole Tet Offensive was blowback for our intervention! The NVA and Vietcong may not have attacked the mainland of the US, but they killed more Americans than Al Qaida did, so again, I don’t see the point of a narrow fixation on a particular tactic, terrorism.
While we’re at it, why not try US intervention in…the US? Think Wounded Knee 1973 and generally, the armed confrontations between the American Indian Movement and the FBI in the mid 1970s (which most Americans regarded as terrorism on the part of the Indians). AIM regarded Indian reservations as occupied land and acted in kind. That was blowback for our Indian policy.
This is not to deny that terrorism can arise from causes unrelated to blowback or perceived blowback. Nor is it to deny that Islamist terrorism may have distinctive features. But it’s very misleading to suggest that Middle Eastern terrorism is sui generis, and confusing to distinguish “Middle East” and “Asia,” as you correctly point out in your post.
This is from Dr Khawaja (of Policy of Truth infamy). I found the dialogue somewhat confusing, too. I think the fact that economists, who are used to thinking in terms of costs and benefits, were stepping outside of their comfort zones (something I wish more of them would do, by the way) goes a long way towards explaining why there is so much confusion.
Yet I also think that there is much to learn from narrowing the terms of the debate. Kling wants to talk about “terror” rather than “armed resistance,” and I think it’s good to meet him on his own terms. This way it is easier to knock down ignorant arguments for all to see. Dr Khawaja broke down a complex misunderstanding (or simply Kling’s bad faith) in a straightforward manner, but sometimes I find that arguing on Mr Bad Faith’s own terms – knowing full well that his argument is being made in bad faith – leads to useful outcomes. Jacques, for example, has become noticeably less hawkish since he first tried to pick on me. He has not necessarily become more dovish mind you, but he has become much more cautious about promoting US militarism abroad.
