The statement means that the plan that the author has is a result of the social and political situation that has come after the place he is in was under authoritarian rule.
Explanation:
The place that the author has been in was under authoritarian rule or under a dictatorship which he calls tyranny. It is evident that it is no longer the case and whatever has come after the said government is not described.
There in lies the ambiguity of the statement. Whatever plan the man has has come after the fall of that government. But one cannot be sure what the plan is about. It could be against the new government, or it could be something that is personal but only possible now that the tyranny is over.
