I don't think so that Khans will join you, rather you would have to join them and be their dogs. They have some specific humor...
Btw. I don't think so we will suffer, UV will not give up. It went through so much shit, that some alliance on their way isn't something new. I wasn't from the beginning in this faction, but I know it's history from forum, in game knowledge and last few months of working together. That's all combined bring me to respect UV as a faction and Napalm as a Leader. If you talk with him in normal way, without rage and insults. Well, than you will see he's not a moron with language problems as he's described by his opponents on forum. Just need to open mind and walk out from your shelter. Fighting in TC doesn't mean we have not to respect our TC enemies. Good luck guys and see you on battlefield.
