My initial impression without better info is that a diversion might have been a good idea but divert to where? Which of the nearby airports were suitable and what defines suitable? Is it the ability of the airplane to execute a safe landing on that airport or the availability of infrastructure to affect repairs and then depart again? How about the availability of emergency equipment at the airport? If there wasn't an absolute emergency such as a fire or decompression but just a single engine failure, which for most of the time frame in question was the case, would you rather land in North Africa or Europe? If you were at 40,000' over northern Algeria approaching the Mediterranean, where would you divert to if PIC under those circumstances? Keep in mind that at the time they made their decision to continue, they had restarted #1 and #2 had yet to display any issues. I'd most likely lean towards Europe. Then again, I don't fly the heavy jets and I am just a low time private pilot. Even with my maintenance experience on airliners and my time in MOC helping to make such decisions, I defer to the crew's judgment in absence of damning evidence that points at an error on their part.
