Well a good bunch of your ships are stuck outside of the Black Sea.
And yeah, you kinda do need those access points.
I mean those blockades aren't really doing anything. I don't NEED those access points lol.
So nah I'm not opening the corridors until you tell me why military aircraft need through my airspace.
The corridors isn't your airspace in full technicality.
You get to fly military craft in the corridors, that means France, Britain, and I get to as well.
