CHP, AKP, MHP none of them any good for Turkey. AKP seems more nationalist than CHP but their mistakes both domestically and internationally are enormous, so they are a bigger threat to Turkey in my opinion. But actually they did most of the damage already. I think some combination of Yavuz Agiralioglu, Sinan Ogan, Ümit Özdag, Turhan Cömez, Muharrem Ince and a few people from IYI parti seem to be the best choice. But not sure I'd keep this list if I get to know them more deeply.
It is a pity that this country has been managed so badly since 1938. When you come from Europe you see what Turks have done to themselves. Turks are their own biggest enemy. Otherwise, how can you explain children being torn apart by stray dogs. Is there any other country like this in the world?
