> From the Turkish perspective, why would they allow someone who supports their enemies to join the alliance?
This makes it sound like Sweden does something that other NATO members don't. That's not the case. Sweden supports the SDC in syria, which supports the YPG, which is connected to the PKK. And this is controversial in several of the countries that do this, including the US.
While it's true that it's Sweden applying for membership and not anyone else, the logical thing for Turkey to do here is to try to pressure the whole alliance to adopt some policy change (such as a terror clasification for YPG, and/or no more aid to SDC and connected groups).
Exactly. Turkey's objection doesn't really have much to do with Sweden and Finland, it's more an opportunity for Turkey to get concessions from other NATO members on an issue on which Turkey disagrees with the rest of NATO: the Kurds.
