46. KEEPING THE WAR GOING
When in Democracy the Senate will seize on the least opportunity to conclude a cease-fire, even if the enemy is on the ropes or you have vulnerable units scattered around. Try not to give them the opportunity. Goad the AI into sneak attacking you - several sneak attacks will cause the Senate to give you full rein for "peacekeeping operations". On the offensive, try to prevent face-to-face situations between ground units, which allow the AI to initiate diplomatic dialogue. Kill enemy defenders with ships, aircraft, and Partisans, preserving other ground units for taking empty cities. Suppress enemy partisans completely, using aircraft next to cities and ground units further out. Wipe out all the ground units you can before taking the first empty cities, because the AI will attempt dialogue (to beg for peace!) at the first opportunity after losing a city.
There is also a trick called the Emissary's Ploy, which exploits the UN and "emissary badgering" to force the AI to refuse any contact with you. Make sure there are no AI units adjacent to the first city you take. Immediately after conquering it, close the city screen and attempt to contact the AI civ. They will refuse you ("enough endless chatter - begone!") and not contact you for the remainder of the turn.
