Hold arms makers accountable for wars.

Rootsaction and other groups could organize a campaign to hold arms manufacturers criminally responsible for promoting wars that were based on false information. They could do this in the same way the Sacklers were held responsible for pushing fentanyl and other drugs they knew were addictive and the tobacco industry was held responsible for hiding the dangers of smoking. All that is needed are some leaked documents showing the arms makers knew that an "enemy", e.g. Iraq, was not a threat, but conspired to withhold the evidence and push for war.
