So, for this turn's mission, I'm thinking we go RC in Australia again, using covert support to stall XCOM's response. If we succeed in bringing Australia up to High Infiltration (or whatever tier 3 is called), we might be able to start actually bringing the entire country over to the Ethereal cause. To that end, I would suggest the following revision this turn:
High Level Negotiation: Certain members of the ruling classes of Earth have come to understand that our victory is inevitable. They are ready to discuss a peaceful resolution to this 'conflict'. We can offer them trinket technology, cessation or limitation of our activities in their country, and positions of power in the new world order. In exchange, they will reduce or halt funding for the XCOM project, willingly provide us with the materials and knowledge that we seek, and promise to assist us when we enter the final stages of assimilating Earth.
We have used knowledge gained from our EXALT captives to create a framework by which the government may be compromised in our favour, with their citizens being none the wiser- EXALT knows a thing or two about keeping large organisations secret. This will make it consideably harder for XCOM to root out our allies, as they are hidden in amongst legitimate goverment employees, controlling things from the shadows. XCOM's usual 'guns blazing' approach won't work in such case, unless they want to make an enemy of the entire country.
Mechanically, the goal of this mission is to contact, negotiate with, and then ensure the safe and anonymous departure of our new allies. Should XCOM interfere, they should be either eliminated, or kept away from the negotiations long enough for them to conclude, and prevented from identifying our collaborators.
A revised version of RC, my hope is that if successful, we would either reduce XCOM's available resources or increase ours- something we could really use, considering XCOM is seriously starting to outclass us techwise. Use of the EXALT token would make our control harder to break, so XCOM couldn't just undo the work of four missions with a single strike.
@ebbor: would this be a valid use of the EXALT token?
Also, would tier 3 infiltration be enough to start converting a country?
