Why democracies don't lose insurgencies

[Cavguy]

put Algeria ? Part of France - not part of French Union colonial structure - which was a democracy. Easy enough to explain it away since the democratic standards applied to Paris did not apply to Algiers, etc., etc. But, the result was secession.

PS: the topic seems OK - and, in the examples, the term "quasi-democracy" would fit many (IMO); thus, slanting the playing field in favor of insurgency "winning". Maybe there are two questions:

1. Why are there insurgencies in democracies ? E.g., Why the War of Northern Agression ?

2. Why are those insurgencies unsuccessful, etc. ?

Algeria was considered an Anocracy by RAND- rule by minority, since the (democratic) French denied suffrage to the Algerian population.

I replied to a PM on the civil war question - as I have read various definitions I have concluded that not all civil wars are insurgencies - mainly because the pol-sci definition of civil war requires "organized military units" among other things, which not all insurgencies (even some successful ones) have.
