Well, you peeked my curiosity, so I took a look.
Hariongori: 19% undermined.
Ehecatl: 21% undermined.
Chimiri: 7% undermined.
That's... not really very well organized if you consider that an attack. In fact, less than 20 of Mahon's 45 systems would count as -not- being under attack by that metric. In fact, only two of Torval's systems have met their undermining trigger - neither is near Mahon space.
[Edit] Look at what Cmdr. Obtuse and his friends have apparently wrought in the last 10 hours - THAT is what an attack looks like. Hats off to that, by the way, well played. Even if I never did anything against either of your powers

(And don't mistake 'reddit stuff' for the majority of the Alliance's pilots, either)
