I’ve received several variations of this question
 since starting my “Question of the Week” series. 
Having never studied the terrorism issue, I’ve
 been ignoring those queries.
But I got several new emails on the topic after 
what happened in Boston, so I’m answering 
simply to make one point. There’s no way to 
create a perfectly safe, risk-free society.
That being said – and with the caveat that I 
have no expertise in this field, here are some 
random thoughts on the topic.
Libertarians want less interventionism around 
the world, and perhaps that will reduce hostility
 against the United States, but some of these 
nutjobs hate us because of our freedoms. So even a perfect foreign policy (whatever 
that even is) provides no guarantee we won’t get attacked. That being said, I 
thinkRon Paul has screwed up big time in some of his criticisms of U.S. actions. 
Being against nation building does not mean you have to be against killing terrorists.
If you want to cause trouble, find a bunch of young men with no purpose in their 
lives and lots of time on their hands. Combine that with religious extremists who 
tell those men that they will get a bunch of virgins* in paradise if they die while 
killing Westerners, and you have a nontrivial supply of future terrorists. I suspect 
part of the answer will have to come from within the Islamic community, though 
I confess that I’m puzzled by the inaction on that front even though one imagines 
that 99 percent of Muslims don’t support terrorism.
Terrorists and would-be terrorists get information from the Internet that fuels
 their hate and provides knowledge on how to conduct attacks. I’m 
rather sympathetic to drone attacks on the scum in the Middle East who are 
directly seeking to instigate/plan terrorism, but I don’t see any feasible or 
desirable way to control and/or regulate the Internet (just like I don’t see a 
feasible or desirable way to regulate video games, even if it was shown that 
violent games somehow inspired Newtown-type killers).
Close monitoring of pro-terrorist websites and chat rooms is a very legitimate 
and proper function of law enforcement and the intelligence community. 
Being a Muslim shouldn’t be a cause for investigation and harassment by 
the government. Being a Muslim who uses the Internet to visit such sites is a 
cause for investigation and harassment (and the same is true for members of 
any other group with a history of violence).
Monitoring of Mosques also is a proper function of government, just as I also 
have no objection of law enforcement monitoring militia groups, environmental 
groups, etc, etc. Obviously, the monitoring of any group should be selectively 
focused on those strains that are believed to espouse violence. I don’t know
 where you draw the line between freedom of religion and incitement of violence, 
but I have zero sympathy for radical Imams preaching hate inside the United 
States and would like to see them shut down/imprisoned/deported if they cross
 that line.
Yes, I’m disgusted by the leftists in the press who obviously hope for a “right wing” link any time there’s an attack. These are the same journalists, by the way, who weren’t even slightly bothered by Barack Obama’s association with Bill Ayers, a real-life terrorist who bombed the NYC police department, the U.S. Capitol, and the Pentagon.
I favor immigration, but I want people who believe in tolerance and hard work. There should be some sort of test, however imperfect, designed to weed out those who do not believe in assimilation. I’m still flabbergasted that the U.S. government is so bloody incompetent that it gave a green card to the so-called Blink Sheik. Such people should never be let in the country and there should be mechanisms for quick deportation (perhaps halfway across the Atlantic) if they do slip through the net.
*I hope these are the virgins they meet.
P.S. Like anybody with common sense, I want’ our anti-terrorism policies to be based on cost-benefit analysis, which is why I’m generally critical of the Transportation Security Administration.
Addendum: I’m getting lots of comments and emails about this post. In retrospect, I can’t claim to be speaking for libertarians, so perhaps I should have used a title such as “What Are Your Thoughts about How to Deal with Terrorism?” Though I don’t think there’s anything in my views that is inconsistent with libertarianism. Assuming, of course, you’re not an anarcho-capitalist. But even if I was in that camp, I would want to voluntarily contract with a private firm that would hunt down terrorists and kill them. Sort of like the group in the new Tom Clancy novels. By the way, I also like the Vince Flynn novels, so I probably am more bloodthirsty than the average libertarian.
