I’m playing France, Viet Nam and Cambodia are my colonies and all of Siam has been conquered. All Siamese units have been destroyed, my war score is 100, and every area is garrisoned by mobile units and at 100 MC.
The above situation has been in effect for several game years. Siam has offered a peace deal multiple times; they only offer cash.
Is it possible to annex or take ownership of Siam?
