Countries are joining the bombing campaign against PISSI, not because more planes would achieve a military objective, but as a symbol.

We Accept That Russian Bombs Can Provoke a Terror Backlash. Ours Can Too.

I am not a pacifist. Effective military action may be justified even despite blowback. But effective military action tends to be concentrated on enemies, so it causes less blowback. Reflexive, ill-calculated military action "because we must bomb something" will tend to be self-defeating.

PISSI hopes to provoke Western reactions that would create a war between the West and all Muslims.
