As far as the foreign troop problem goes...
"I'm so sorry, but new construction on the roads leading to your military base means that we're going to be unable to guarantee supply deliveries such as food, fuel, or new stocks of ammunition for the foreseeable future. And naturally, new environmental regulations ban the operation of Helicopters in this region, due to it being the habit of the endangered Red Wild Beak... Naturally if you wish to withdraw your troop garrisons in the face of your untenable supply issues, my government will make every effort to cooperate."
