In all seriousness, I still might argue its better to burn the money (or delete a bunch of numbers on a spreadsheet) than have it go to the arms industry. Yes, that money does go to pay wages in the US, but thats basically just the broken window fallacy in action - we see results of propping up the arms industry but will never see the benefits of not taxing citizens for that money in the first place.

Having a massive arms industry means having a powerful lobby whispering in everyones ear. I think the War on Terror cost the US something like $2 trillion. Granted in the US, we just stack on debt, but thats another issue. As far as spending money on other, less destructive things, we've proven that money will just be squandered, I'd rather it not be taken in the first place.
