Erdogan is right that UN is not representative.
But
Turkey is probably never going to get into the UNSC.
1. If any Muslim country has to get in (by religious consideration) - it will be one of the Arabs. Odds are - Saudi Arabia.
2. Turkey is a Secular country, so you don't get the benefit there even if the criteria were to be added.
Lastly. Get in line. The next country to join UNSC will be India. Period. If we can't get in, you can be sure, you're not going to make it.
So I don't know why Erdogan is worrying over this.
Have you guys felt like you missed something obvious ?
