And since when is improving the lot of your allies when you do not considered acting against an alliance? Improving the military of one of yours allies, and the technology of another to make the alliance stronger as a whole?
I'll readily admit there was a personal interest in doing so, but that was more in what was offered by them in return.
Let us see: 20 RP (Warfare II) for 1 AP. What does that read like? Indeed, it does sound as though he signed a deal that benefits you, a potential and, in time, certain enemy to the alliance, a much greater benefit than it does himself, or anything he could come to share with the alliance. Making what ultimately comes down to the alliance's strongest eventual enemy even stronger, without empowering himself as much, is already and of itself sabotage of the alliance.
Therefore, I could only conclude he supremely concerned with his personal might, as was made all too clear by the context, directed against me, of the same post, and altogether unconcerned about bolstering the alliance's enemies. The only conclusion to that is that, expecting me to invade him, he was trying to gather power to preemptively do so instead; logically, the only sane answer I could give to that, as he'd eventually turn on me, to your benefit, one way or another, was beating him to it.
While GWG had not made the same mistake, I doubt any of us can dispute that, once I moved preemptively against sjm, GWG would pitch in for his side. As if an alliance between three individuals who started in the very same region wasn't tenuous enough, what with the only way of properly defending Earth being controlling its orbit.
