I have a different viewpoint to most on issues such as this. We seem to want to allow the populations in these countries to enjoy “freedom and democracy” that we are fortunate enough to have. The sort of freedoms and the democracy we have in the UK have been built up and developed over centuries. They could not have been introduced overnight. But that is precisely what we are suggesting should happen in the places in which we are interfering to a greater or lesser degree (Iraq, Afghanistan, Tunisia, Egypt, Libya to name a few).
The difficulty is we have no idea why these places are ruled the way they are and even less idea how their populations will react when given their “freedom”. Most importantly we have absolutely no idea who the “rebels” or “freedom fighters” to whom we are lending our support are or how they will behave if given a sniff of power. Apropos Libya in particular, this article makes interesting reading:

So to answer the question, we don't know what the "right thing" is and we'd do better minding our own business. (Cue for all the Human Rights and humanitarian aid activists to take to their keyboards).
