User blog comment:KrusH HsurK/Earth, Capital of humanity, but lacking of its own capital?/@comment-1388547-20120508211538

I suspect the bit in Vancouver was a matter of Vancouver being chosen as some sort of major center of Alliance activity, as opposed to a civilian capital -- sort of like San Francisco in Star Trek, though San Francisco has the excuse of having a significant naval presence in the area today and having been an even more major military base in the past. But hey, Vancouver is a nice city, so why not locate an Alliance base there?
