We already have finland. Not sure why a red/blue mix would be a problem.
There's not a country in the ME that doesn't have a mix, except maybe Syria and Yemen.
Finland would probably receive limited stuff to make the deck functional; but having M1A2 and Smerch in a same deck it's crazy and certainly far from game's scope which is Cold War. Time frame it should be anyway capped earlier than it is and many designs shouldn't be there as they're clearly 2000s stuff.
A Kuwait deck would have a lot of unicorns, true, but not much else and would be like a sandbox deck where you can take every unicorn you like. Is this what we are looking for?
