Justis, you are either naive, foolish, or deliberately peddling falsehoods.
There was a monumental amount of work still to do to after Rudd's initial change-of-heart was put in place before the tragic trade was completely stopped.
The entire suite of policies had faced multiple court challenges, the full force of the ABC/Fairfax, an entire 'refugee' industry, all attempting to get the conveyor-belt of disaster back on track.
Abbott needed the hide of a rhino, the patience of Job and the backing of his party. You may argue that Rudd would have had all that plus the required level of fortitude to see it through, I would argue against. Either way to say that the work was done and 'OK a few boats got turned back' so understates the level of the problem which was faced as to be truly bizarre.
