no no thats not what i meant. im wondering why madara didnt use izanagi to un-ghost izuna since im thinking he probably knew the jutsu at the time.
i fully agree with your point.nagato would have revive jiraiya along with the village if he could,so there must be a time limit.either that or theres some other obscure reason why he cant,like maybe the technique has a limited range or something,or it requires some kind of body to return the soul to ,like the villagers were probably still intact and madara had an edo vessel while jiraya was probably semi-decomposed by then.
that got me thinking,,,technically madara himself was also long dead,despite being a edo.but still he could be revived.so maybe there are other factors other than time that determine whether or not a person can be revived
