Better to dish it out separately as this topic will get heated up in the comin days.

NATO: Turkey outlines demands on Finland and Sweden membership
Turkey said it could back Sweden and Finland's NATO bids if they stop supporting terrorists and lift export bans. Aspiring NATO bids require unanimous approval from existing members to join the alliance.
Turkey has long accused Nordic countries, especially Sweden, of harboring extremist Kurdish groups as well as supporters of Fethullah Gulen, a US-based preacher wanted over a failed 2016 coup.

Sweden, in particular, has a large immigrant community that hails from Turkey.
Many of the migrants are of Kurdish origin and some have been granted political asylum after decades of sporadic conflict between Kurdish groups and Turkish security forces.
Nordic countries have always been known for being safe haven for PKK members and supporters. Its partially due to immigrants from Turkey to these countries being mostly Kurdic origin. It was no coincidence that a group of PKK supporters flied a PKK flag in Stockholm today:



So, discuss the aspects of Turkish concerns over Sweden and Finland as they apply for NATO membership here.

And before we have someone come up and cry how YPG is not PKK:

Worldwide Threat Assessment of the US Intelligence Community
The Kurdish People’s Protection Unit—the Syrian militia of the Kurdistan Workers’ Party (PKK)—probably will seek some form of autonomy but will face resistance from Russia, Iran, and Turkey.
Senior State Department Officials On the Situation in Syria (October 10)
SENIOR STATE DEPARTMENT OFFICIAL ONE:
And to do that we need a partner on the ground. That partner has been the SDF, a major component of which has been the YPG, which is the Syrian offshoot of the PKK. That, of course, is the problem for Turkey, which has been suffering horrific terrorist attacks from the PKK for now 35 years, since 1984.
Turkish intervention could trigger Syria's 'second great war'
US diplomats and officers of all ranks who have worked with him for the past four and a half years are full of praise for Kobane, whose nom de guerre was Sahin Cilo when he was a militant in the Kurdistan Workers Party (PKK). The PKK, which has been fighting Turkey for Kurdish independence, and now autonomy, since 1984, is on the US State Department's list of terrorist organizations. Turkey likes to remind Washington of this irony, and it's the reason why Kobane is unlikely to be rewarded for his prowess on US soil anytime soon. His real name is Ferhat Abdi Sahin and he is on Turkey's list of most wanted terrorists.
