I agree that war is hard to justify. However, I believe that inaction is also hard to justify. Also, no, I obviously don't have a clear formula.

  I think you may have stretched point 3 a bit. The US is wrong to use the tactics they use in warfare. The US is justified in removing a transnational Religious Zealot organization of tyranny supported by most of the local mujahadeen leaders that they put into power. They do not represent most afghanis. So leaving them in power would have been the preferable choice? Have you polled afghaniis on this question? Or was there another way to resolve the problem? And if not the us, then who, and would they even have been able to? Is it not justified for a country to try to fix a mistake? 

I do not own this national post blogger who I believe has his own separate blog with the same material, the author is somewhat irrelevant.

The disease is not specifically the usa as other countries have acted and act just as them, just with less resources. The disease is humanity. So even, if the cause were to be dealt with(usa), that does not automatically remove the symptom unfortunately, even though it is not really a symptom, but a separate symptom battling with the first symptom after having been helped out by the first. 

Again, I do not own him and therefore will not defend him.

In the case of America, there is still hope as they are not beyond reason. On that line of thinking every country should go to war with every other country for supplying weapons and such or for all other infractions. 

Moreover, there are still other ways to try to address the problem, whereas, in the case of the taleban, I do not believe that was so. If you could enlighten me as to how, I might change my tune.

The problem I find with the left on this is that they are great at pointing out wrongdoings in this area, but are solely lacking in alternatives, and ways in which to work with what we've got. However, I am open to changing my mind.
