Initially unwilling to respond to bep's ignorance, I am moved to reply in case it is genuine.
Most countries of the world, working from ICAO guidelines, have legislation in place that allows four engine aircraft that experience a failure of a power plant to continue their flight to destination if certain parameters are met. The parameters are allowed to vary under ICAO doctrine.
The statement, "Land at the nearest suitable airport", is simply Wrong, Wrong, Wrong.
I do not know who has polluted your information with this idea, but rest assured that all the aviation industry know that you are not only wrong, but that in pprune terms, your credibilty as a contributer is equivalent to an Ebay fraudster.
Good day to you
