It's exactly the point of the discussion. Everyone was referring to "the invasion".Now you've altered your argument to 'conventional military campaign'. That was not the discussion - that's called a strawman.
Which means the military campaign is not over.
The invasion was the conventional military exercise - it was a success.
If the aftermath - which was the administrative part - was done properly the military part would be completed.
The military campaign is not over because the aftermath was not adequately planned and executed.
