It's not a myth. If the Internet were running RIP instead of BGP
For the Internet, I believe it was indeed a myth.  I wasn't there,
but according to someone who was:

I believe the mental->mythical sequence went something like:

- some people (Paul Baran among them) were interested in ways to build
  communications networks that could survive lots of damage, and came
  up with the idea of distributed networks that could route through
  multiple redundant nodes
Read the paper here:

Redundant is probably the wrong word, failure-tolerant is probably more accurate.

- the US was in a cold war and nuclear arms race

- a nuclear attack could inflict lots of damage to communications

- the Internet was eventually, to some extent, built as a distributed
  network with routing through multiple redundant nodes (if nothing
  else, the protocols that ran it were capable of such)

- the Internet was therefore built to survive a nuclear attack
Roughly modeled after something designed to continue to route packets following the loss of a few nodes.
