Both sides are using terrorism on civilians but the label doesn’t stick when the explosives come from a plane or gun barrel. Both sides are US allies and this can be solved with pressure from other states too.

The "both sides" diversionary tactic doesn't help anyone in these debates. It's the favourite excuse of every dictator and bad guy.

The radical Kurds aren't going to win anything by engaging in it nor will the more moderate Kurdish groups gain anything by quietly supporting them.

Turkey has much to lose in the years to come by exposing their soldiers in Kurdish majority areas and they are only further alienating themselves from Europe and the world, especially if they get too zealous in the process. They haven't even faced any real resistance yet since they focused on Arab areas first. Their decision making won't be without cost.

There's no way this will be easy ride for them. Nothing in the middle east is ever like that. This is just downtime between the next major conflict. There's only so much to gain for anyone involved.
