Georgia? It was under Bush 43 that Russia invaded that country.
But you are right, sort. By ELIMINATING al queda's (remember them?) top brass - and um, what's his name? Oh yeah, bin laden - the vacuum left was filled by the generals and soldiers of Iraq's Baath led army that Bush inexplicably dismantled. They created isil.
N Korea? Come again? President Obama kept that little smokebomb pretty much at the level Bush left it at. It WAS under bush's watch that N Korea, and al queda's HQ, Pakistan, GOT NUKES IN THE FIRST PLACE.
ALL three you stated were under George W Bush's watch or because of actions he took or did not take.
If effectively crippling al queda was a factor (isil still was going to happen) then thank the Gods Obama at least got rid of them before THEY killed someone YOU know.
Perhaps next time you should LOOK UP something before blaming someone else for what HIS PREDECESSOR caused,,,
