Narrative:
I showed up in operations completely rested at XA20Z; 1 hour 45 mins prior to our scheduled departure of XC07Z. The captain and I completed all duties in a timely manner and arrived at the aircraft about 1 hour prior to scheduled departure. Deice procedures were in effect and push times were given to keep aircraft on the gate and to keep traffic moving. We ended up pushing 39 mins late at XC46Z. The entire flight was completed to a low visibility approach and we blocked in at XJ15Z; 55 mins late. What made this flight unsafe was the fact that we were unaugmented. The fatigue experienced was well beyond what is considered safe. Flying all night; back side of the clock; international without a relief pilot. The block time may show less than 8 hours (7 hours 29 mins) but I was in the seat for more than 9 hours.
