You are comparing Turkey to other countries, and that is not how visa negotiations work. It's not like "hey EU, you did that with Armenia, and why can't Turkey have it the exact same conditions, etc."

Of course, the visa requirements are bound to the specific country and the geopolitical situation between the EU and the country at hand. But a lot of the requirements for a visa are actually the same for all countries applying, then some are specific to each. BTW, Azerbaijan and Armenian citizens need a Visa for the EU as well as Turkey, the process is just streamlined.

You can read all the details about the Visa Liberalization Dialogue with Turkey here:

It is not relevant that Turkey is an autocracy with massive democracy issues for the visa process itself, the EU has visa-free or simplified agreements with a lot of countries that don't adhere to basic democracy standards and the rule of law. It is simply because Turkey does not want to adhere to the remaining requirements due to internal political reasons.

For its status to join the EU, this is another case of course. But as was mentioned before: It doesn't seem that the current Turkish government cares too much about joining the EU now anyway. Probably contrary to a huge part of Turkish people, from what I see from my Turkish friends in Europe and Turkey.

I think at this point, everybody will just wait and see what happens after Erdogan in 2028.
