What is even cooler is that he wouldn't have to destroy the machine for
things to come back to normal. All he would have to do is decide to
destroy the machine (then of course follow up by destroying it, but to
actually affect the future all he would have to do is decide to destroy it),
and in fact someone stepping on a bug somewhere in Galbadia could affect
his decision due to the butterfly effect and thus someone taking a shortcut
home to Galbadia and stepping on that bug could have saved the world.

So really, it's all that Galbadian's fault for going the long way. ;]
