Resilience was certainly a goal of one of the studies which inspired the use of packet switching in the ARPANet (Paul Baran's work at the RAND Corp, not so for Donald Davies's work at NPL) but AFAIK it was never a explicit goal of the ARPANet itself or of the IP-based networks which replaced it. So it'd be interesting to see any contemporary documents which suggest resilience was actually a goal.
@cypnk Nope, sorry you're reading more than is there. That's not even close to contemporary, a partial story, at best, and rather Air Force centric but still there's no link from Baran's second-strike ideas, (as opposed to his and Davies's packet-switching ideas) to the objectives of ARPANET which was mainly about making DoD funded research more efficient.
