>>>>> The data these people have access to is quite an important intelligence asset:

My question would be why it took them so long to go after the postal service if they've thought it was such a high value target??

Everything is relative, including time. Nothing tell us how long they were trying to attack USPS or even how they were trying. This is just a case were they tried to do it one way, they succeeded and they got caught. There's probably multiple incident that public doesn't know or even that intelligence services doesn't know.
