We have been at war with PKK for nearly 40 years and lost tens of thousands to the war. The war on PKK didnt wipe it out back then, and it didnt wipe it out during AKP time. It was clearly not going anywhere and Erdoğan tried giving diplomacy a try. I know PKK is horrible but if çözüm süreci worked within reasonable boundaries it would have been much better than perpetual war forever. Those who attack the process so much have only one thing in mind: revenge. Not peace at homeland, not stability of the country and the region, and not the future losses of life due to the war.
What is important is that Erdoğan gave them a chance but they proved to the whole world that they never even wanted peace. Now no one can blame Turkey for roasting them. And what is more important is that in the past decade Turkey improved the military doctrine and the defence industry so that the army effectively fights terror instead of constantly staging coups.
As we speak every square inch of land in the southeast is monitored by tens of drones that drop bombs on you, scatter you into pieces, and shoot the pieces 20 ft up in the air before you could finish saying "Biji Biji Kürdistan" if you are stupid enough to try to sneak into Turkey or do another malicious activity. This has effectively finished terror in Turkey. The past few months have been safest in turkey's recent history but of course some people conveniently forget that.
Last but not least we are finally marching into qandil, with almost no casualties (maybe exactly none). We are pushing the battlefield away from our borders. No previous government had the courage or capability to try this.
In summary, Erdoğan did what every reasonable leader should do. He gave the enemy a chance and proved to the world that they are not a negotiating lot. Then improved his military to have the upper hand and started destroying or at least pushing the enemy away from its territory. If anyone has a problem with that they can go to hell. We are not a gang, we are not a mafia, we are a goddamn country, our first priority should be peace not revenge and we should always leave room for diplomacy. And if you are so "nankör" to not see that the war on terror in Turkey has finally ended during Erdoğan's time then again, I hope you rot in hell.
