Two of those sound like completely unreliable and unsubstantiated opinion from Imperial partisans. Only the one from Nom Anor sounds like it might be worth shit.TC Pilot wrote: It's cropped up in the sources at least three times that I've seen so far. The first is the quote from Nom Anor already provided, and considering he was knee-deep in bringing down the Empire since at least as far back as Crimson Empire, he's something of an expert. Less authoritative is the assessment made by Captain Vana Dorja, an Imperial officer, in Destiny's Way, that the Empire would have crushed the Vong as soon as they invaded, prompting Han to rant about how they'd have built some stupid superweapon, the "Nostril of Palpatine," that would have blown up in their faces. Lastly, there's Betrayal, where a relatively young Intelligence officer flat-out says to Wedge Antilles' face that the old Rebels shouldn't be so smug and self-righteous because the Empire would have "kicked their teeth in" or something like that.
Also, the ability to kick an enemy's ass is not the only standard by which the quality of a government is measured. Its important certainly, but so is the regard a government holds for the rights of its citizens.
