So if you where living in Nazi Germany you still saying these words?
I know a nation need to be powerful to defend it self from evil but you don't have to be evil murdering millions of people because you don't like their faith.
I'm just stating the obvious - wars are inevitable and hence every nation is directing significant ressources to self defense (and quite a lot to offense too).
Related to the supposed inevitability of war AND nazi Germany, I recommend Nicholson Baker’s Human Smoke. It’s a good catalog of the choices, both economic and philosophical, on all sides, leading up to it (and contrasted with pacifists).
I think it's a lot more nuanced than this. Defense can be perceived as threatening and cause others to increase their defense, as per Balance of Threat theory and the security dilemma, creating a feedback loop (arms race) that leads to a lose-lose situation, primarily for the weak, but also eventually for the strong.
I am not advocating against defense spending as a category. I am saying it needs to be done skilfully and as a last resort, with the understanding that it is only coherent in a world without a unipolar security architecture, and is therefore hopefully temporary.
