Which, as the UEF would point out, proves exactly nothing, since the GTVA, for all its military prowess, knows nothing at all about the Shivan strength or shivan strategic objectives. It can't even reliably defend humanity against the displayed shivan strength at Capella. Thus, their ability to blow up ships is quite possibly completely irrelevant when it comes to the question of how to deal with the Shivans. But that is a different discussion, one we had ages ago already.
Then there's the simple fact that Ubuntu isn't
meant to protect anyone from shivans. As Battuta pointed out, its objectives are economical, social, and scientific, not martial.
Ubuntu citizens are not too likely to turn on the government that has led them into what appears to be the greatest era of prosperity in human history. They're likely to believe more in the great towering skyscrapers on the Moon and the inhabitation of Mars than some obscure, distant video clips of aliens blowing stuff up. Furthermore, the stuff they have seen blown up were blown up by the GTVA, a clear aggressor (in their eyes) and not some random alien race who they've heard nothing of for 50 years.
I would believe that the average Ubuntu citizen's reaction to seeing footage from Capella would be more along the lines of "Yeah, Shivans are ****ing scary, we knew THAT already. Why haven't you come up with a better solution than 'Shoot them till they stop glowing' yet? What is that you say? You don't have the R&D infrastructure to do that because you poured every bit of money you can spare into the fleet? Well, that is a quite a conundrum, isn't it?
Hmm?
Oh, yes, of course we'll help you build up defenses. Of course, that would have been a bit easier if you hadn't smashed our fleet and its infrastructures, but since you
obviously have more experience in such matters, we shall defer to your superior judgment.
Oh, by the way, it would really help if we could get the Elders back. Cos, you know, dem Bookworms be badass."
