Well I don't want to switch countries and push that third country in the hole even farther.
Sorry, but I have to comment: Who said you have to push the third country even farther? Au contraire: Being a well organized squad, you could actually move things in a different direction.
Switch to Knights and then do a nice organized bomb raid on rookland. Maybe just flatten a town or two to stir it up. You would make a nice darbar, and if they notice you are not doing a strat run but are threatening their bases, you will see defenders upping. If not, they will lose a field, which sends a nice message too.
A single player doesn't have this option. Four or more players like you guys who are knowing what to do, have.
