PISSI is rebuilding its forces in Iraq, and is launching guerrilla attacks.

The numskull is directly responsible for this. If he had kept supporting the Syrian Kurds of Rojava, they could have rooted out PISSI.

I think the numskull didn't want a full victory over PISSI. The fight, for him, was an opportunity to tell a superhero story for political ends. In superhero comics, a villain that dies is no use any more. So they keep allowing villains to make comebacks. In the same way, the numskull saved PISSI at the last minute so it could make a comeback and give him a chance to tell more stories.
