Yeah, liberated. Algeria is no longer an explicit French colony, just an effective one (they now skip the middle man and exploit it directly through trade agreements). It turns out its quite difficult to magically create a prosperous liberal democracy post-revolution when isolated from both international trade and the political sphere of the hegemon, and when the militarized state structure that was necessitated by the war effort can quite easily be co-opted by certain elements in the state savvy enough to purge any opposition that would prevent them from re-establishing trade relations with the same international business interests and neo-colonial enterprises as before, that would happily provide support and funding in exchange for unequal trade agreements and repressive domestic policies that benefit the oligarchs and their foreign partners at the expense of popular support and the goals of the revolution.
>It’s not like they turned it into a democracy or even tried to
How familiar are you with the cold war, and especially the third world movement? Do you know what happened to the democracies?
>more atrocities targeting civilians or former Algerian soldiers serving in the French army
Did you expect them to grant amnesty to a domestic reactionary fifth column, who in the case of both cuba and essentially every other third world country during that century, immediately began programs of terrorism and destabilization with foreign support? I'm not talking about the civilians who should've been securely repatriated, but a lot of those informants and French soldiers where not peaceful bystanders. The french state would not have been able to carry out their programs of torture and terrorism against the civilian population without their help.
I'm not exactly condoning or celebrating reprisals or violence but once again, all of these things become inevitable when a country is colonized and repressed, so I'm not sure why you place the moral condemnation on people that will inevitably resist an occupation rather than the instigator.
In any case, what's your ideal scenario? That a brutal struggle for national sovereignty somehow manages to secure their freedom with limited violence or guerilla tactics against an infinitely more funded and lubricated colonial machine, and immediately institute a parliamentary democracy that will avoid being subject to a purge or military coup (as was the case in Algeria) or outright foreign intervention (in the case of Allende, Sukarno, Park Chung Hee, Goulart, and literally too many others to list).... somehow? Or instead should they have just rolled over and assist the French in violently pacifying the population, or in the case of Cuba help maintain Bautista's dictatorship solely to prevent civil instability at all costs, since national sovereignty clearly cannot be attained in a manner you deem proper.
