EDIT: Word of God:
I was just wondering, is it possible that the Terran-Cyrvan war was an analogy for the 2003 Iraq war?
No.
I'll try to explain a bit away here since I gues the similiarites don't exist as explictly as you state them...
less advanced government
"advanced government" hmmm... This implies that there is a certain evolution of governments... while a succession or a cicle of certain state types has been theorised throughout history, an evolutionist approach to that particular subject I don't know of -- authors tend to find virtues and vices in every form of government and weight them differently --
unless of course you are referring to technological advancement ... than see the following:
a powerful, advanced military launches an invasion of a weaker, less advanced government,
which is the premise for most wars in recorded history as you don't wage wars you don't think you can win in terms of symetrical warfare
with the intent to disarm them and install their own form of government, because they do not trust the leaders of this government with the weapons they have
not specific enought of Iraq War ... most wars that ended in the absorbtion of the defeated states territory in the victorious state came with the installtion of a new ruling class/caste in the conquered territory; a change of government or at least state policy dictated by the victors is also common enough even when no territorial gains are made in the end (peace treaties...)
many civilians on the Cyrvan side did not support the war,
civil enthusiams towards war is a rare occurence in history ...
Also after the war, there were groups of LSF Terrans who liked the CSA, and groups that did not, similar to how the opinion of the US is polarized among Iraqis and other Middle Easterners.
Common enough in post war politic envoirments - there are those who arrange with the new status quo and those who seek revenge...
Both sides also have a tradition of a monotheistic God, but the details are different
Which is true for large number of randomly selected groups you could pick for our worlds population and compare to one another
Many people consider them to be arrogant
They are Space Elves - its part of the cliché
(My dear Lady Isa, I meant no disrespect...)their government makes a habit of interfering with other civilizations
a) define what you call "interfering"... in an open definition market based economies interfere with other civilizations by forming an inter-civilization market
b) often attributed technological advanced races in Sci-Fi as part of the "stop being silly and listen to us 'cause our civilistation is more advanced"-cliché
ostensibly for their own benefit, just like the US government does to other countries.
It's a sad refection on the political culture in western countires that acting for the benefit of another nation is not considered a good policy
