User blog comment:Dettles/Why didn't Marco protect whitebeard's terrorities?/@comment-5.65.80.30-20130602125911

I would say they did, The WB pirates aren't strong enough now to protect all islands, most of their terrotires would have been attacked, with the loses they suffered they can't take on Big Mom and Blackbeard. Let alone if loads of other pirate are attacking other terriotries. The BlackBeards may have gone from island to island, but how many of them had already been taken by people like Kid, or Doflamingo? Crocidile's looking to rebuild? They did save lands, just they couldn't save them all...
