Erdogan is shyt
I like the guy. He's smart. Very Machiavellian. He's like a Turkish Putin. He knows how to play one side against another better than anyone else in that region.
It's about business and diplomacy
Of course. Poland I think is just looking for allies and spreading their net far and wide. Poles and Hungarians know that in the future they won't be able to count on any sort of help from Western EU - if anything they'll be more of a political hindrance. This is why they're looking for new alliances. US atleast while Trump is in office will be a reliable partner. And of course Hungary-Poland - that's almost like an unbreakable bond. The V4 helps too along with countries like Austria, Bulgaria, Baltics etc which aren't keen on forced migration. Even if Turkey doesn't end up in the EU, they can still become better partners with Poland. Poles generally don't have much of an issue with Turks. The Turks actually are regularly targeted by radical Muslims for being 'kuffars' and being too European and liberal.
Even if Turkey never joins EU, they are the gatekeepers preventing, or allowing, millions of migrants - which include terrorists, criminals, perverts, agents from hostile governments, thieves, etc from flowing into Europe. The EU leadership knows this damn well so there's only so much they can do before they really upset Erdogan, he sides with Russia, and screws over the EU. Or funds some radical group to start some new conflict fought through proxies.
arrests are solely made to weaken domestic opposition and are not upholding basic legal standards
Thousands of people tried to overthrow a democratically elected government. They're lucky they weren't shot. When you try to overthrow a government or support a coup you're going to get put in jail. It was 10k people that were rounded up and arrested, not millions so no its not like he suddenly shut down the press, shut down all the opposition parties and deemed them illegal, etc. Turkey is not a dictatorship. I've been to Turkey - only once and for a short period of time but it is a beautiful country and the people were generally very friendly. There's even gay pride parades in Turkey (even though the marchers tend to get beat up) but nonetheless that just shows that Turkey is far more liberal than any other Muslim majority country.
Erdogan wants to use them as hostages against other countries
It helps negotiating position. Israel, Palestine, Russia, Ukraine, United States, all do similar things. This is nothing new. If someone is valuable or has valuable info they will be captured, perhaps even tortured, so the state can get what it needs. Or they'll be locked up in a cell for a rainy day to be used as a bargaining chip.
Turkey can be a great economic partner and help us politically in certain situations. Erdogan won't forget that only the Poles and Hungarians met with him and other EU leaders didn't. Turkey does not have good relations with Putin - it's been rocky at best. Lets not forget Erdogan and his sons made billions off oil trafficked by ISIS, allowed Europeans to go to those lands no questions asked to fight for ISIS against the Kurds/Iraq/Syria. Also, if I remember correctly the Turks shot down a Russian jet. Turkey has been wisely playing the NATO and Russia against each other. Just take the example of how Turkey wisely drew NATO and Russian suppliers of air defense systems (patriot vs s400) against each other.
What do you guys think about Georgia though/??????
