President Erdogan does a glorious diagonal comparison.

From City AM:

US President Donald Trump has taken a hard line against Turkey over the fate of American pastor Andrew Brunson, who has been detained in Turkey for the last two years, accused of links to the banned Kurdistan Workers Party (PKK) and the Gulenist movement which has faced a crackdown after a failed coup in 2016...

In a New York Times article at the weekend Erdogan threatened that NATO-member Turkey could “start looking for new friends and allies” if the US did not reverse its trend of “unilateralism and disrespect”. Turkey also wants the US to hand over Pennsylvania preacher Fethullah Gulen which it blames for the 2016 coup attempt.

Woah! That's not how prisoner exchanges work.

Brunson is an American held in Turkey against his will; he wants to go back to America.

Gulen is a Turk in exile in America very much under his own will; he does not want to back to Turkey.
