According to the aliens, if you manage to escape human race will live and be valued as allies.

Firstly via bruteforce (or frequency analysis):

the three letters ?re? ???

And with correct method, when you could see "1" is "e" and "1=1" is "t":

When "1=1" is "dash" and "1" is "dot" and "0" is separator/space:
- .... . - .... .-. . . .-.. . - - . .-. ... .- .-. . ---... -- .- -.
THE THREE LETTERS ARE: MAN
