The two provinces in question are STILL part of Georgia, regardless of ONLY Russia recognizing them.
Russia has been occupying these two provinces for quite a while (as peacekeepers no less), even though the rest of the world recognizes Georgia as an independent country. The details of who exactly started what are still coming out on this, so it is hard to say who started what - but I can be pretty sure that Georgia did not attack into Russia...

Should we start issuing citizenship to Mexicans, and when they return home, annex northern Mexico or Baja saying that a number of US citizens live there and we are just protecting them from lawless militant police forces?
