De Garis has luddites on one side of his war. That group has historically been impoverised and has lacked power. The government may well just declare them to be undesirable terrorists - and stomp on them - if they start causing trouble.
We can see the environmental movement today. They are usually fairly peace-loving. It doesn't seem terribly likely to me that their descendants will go into battle.
