I'm kinda liking the idea of declining the MPP - even if they're right about the War Happiness - we'd really rather stay under the radar, unless someone is getting an overwhelming victory.
However - I DO like the idea of giving GONG flight (with a strict promise to NOT give it to BABE).
And then, give MotorTransport to BABE - perhaps in exchange for some kind of non-aggression (& Non-tourism

) arrangement. [and if they give it to GONG... well, that's not our fault]
Saber won't be able to prove we gave MotorTransport to BABE... FREE could have easily and plausibly done that... and let's face it, we don't have an active treaty with them right now anyway, through no fault of ours.
It's also not provable that we were the ones who gave flight to GONG... but even if we did, so what? Only FREE would be upset by this, and they haven't had a treaty with us in a long time.
Maybe we can even get consensus on this approach?
EDIT: @Paul - I don't think it's suspicious if GONG gets flight and doesn't trade it. Heck, if asked, we can even admit we made that trade! Only FREE would be upset... and hey - it's payback time for Hoover & ToE.

It's possible Saber would even be grateful that we went out of our way to prevent Flight from falling into the hands of the BABEs.
