Don't you get how many running storylines will suddenly be destroyed if something like that (the fall of the WG) were to happen.. which is why it won't.
yeah i didn't mean the wg would fall for good. i think the revolutionaries might end up taking them out in the sense that their influence over the world will end. i think with vegapunk they will end up returning to power with some new technology that will let them wipe out pirate crews and even entire nations easily. probably vegapunk will invent his own weapon that will rival the ancient weapons. also the pacifista will likely get an upgrade and be much more powerful. although i expect them to come back into power right around the end of one piece so it ties in with luffy finding out the true history and trying to do something about it.
