So I don't have to search back through the thread, could someone remind me what the whole point of the Crusade is? I must have blanked it out.
Reclaiming the Jericho Reach and reincorporating it into the Imperium.
Isn't that a bit harsh, MILLANDSON? They're speculative, not worthless. Their worth lies in the idea that if you wish to consider these issues, then the practicality and the volume of the endeavour begins to take on the appropriate scale. YMMV as to whether the Imperium can keep this a "perfect secret" (I once again point out that it remains, regardless of how hokey it is, an easily exploitable story line from both sides of the argument), but BaronInveagh's post does indicate the scale likely involved.
The problem with that is that since all the numbers involved are pure speculation, the result may easily be a few orders of magnitude greater or lesser. The only thing known is that it's going to be a really massive undertaking. Did anyone doubt that?
