Although I support virtually all tenets of the libertarian ideology, including the radical ones (NAP, Anarcho-capitalism, crime theory, Austrian economics, non-interventionism, etc…) I am completely opposed to one tenet, and that is what I call libertarian pacifism.
The vast majority of libertarians for instance oppose the bombings of Hiroshima and Nagasaki. They also oppose Israeli wars. I think that’s just crazy. Although I strongly support non-interventionism, for example I think the United States should withdraw all its troops from abroad and remove all its bases from other countries, I cannot even begin to understand the libertarian opposition to defensive wars.
I am an Israeli citizen, and I see weekly how Hamas rockets hit southern Israeli towns. Hamas was a democratically elected government. The vast majority of Palestinians have voted for this organization. These people are therefore responsible for Hamas actions. Hamas uses indiscriminate weapons against Israel. It specifically targets civilian centers. I think it is completely natural for Israel to retaliate against these weapons in the same way, that is also to use indiscriminate attacks. It is true that some Palestinians who did not vote for Hamas will be hurt, but it is Hamas that should be liable for the death of these innocents. Why? Because by choosing to fire at Israel they leave Israel no choice but to retaliate, and any retaliation in war has collateral damage. There is no other known way to fight wars. You cannot let Hamas get away with destroying civilian Israeli life because Israel cannot break NAP. This is crazy! And please don’t give a Guerrilla war as an example, it is completely impractical.
The same is true with the nuclear attacks on Japan in 1945. If any other method was used, the Japanese would have not surrendered unconditionally, and such type of surrender would have only invited another attack. Libertarians are usually critical of identifying the individual with its state. But that’s how most people see the world, especially the enemies, whether the Japanese 60 years ago or modern Palestinians. They see their country as a person, and if that person was merely hurt, but not surrendered unconditionally, they will see this as a victory and will act accordingly. If you want to stop the aggression of your enemies, you need to destroy them, kill 5 citizens for every citizen they kill. Otherwise they will not be deterred.
Now you can conjure libertarian theories and logic here, but you have to look at reality. This is how it works in the real world. Hezbollah doesn’t stop its assaults if you only kill some of its members, they stop their assaults when you hurt the civilian base that supports them. They stop their assaults when the damage both to them and the civilian population is so great that it destroys their motivation. After they see hundreds of destroyed villages, and grieving mothers, only then they consider stopping their aggression.
