Here's an example of how people lose their arguments. A laudable objective. Stop war. I concur with that. I hate war as well. But the author forgets few things. That a state has to first and foremost keep its citizens safe and there are competing ideologies and missions which stop them from doing so. Think about the police. Why do you need them?
Second is to make silly comparisons. Don't make an aircraft carrier and instead use the money to build water systems. Good. Whose going to pay for that? Running costs for the next 30 years? The American taxpayer will pay for the world's water system? There's that little matter of democracy to worry about.
When people make arguments like this,, they cause more damage to their own cause. Just noise.
