True but most of them operate in third world countries with pilots and maintainers that have, at best, third world qualifications. Many were exported from Europe when they were due for major maintenance and that maintenance was never carried out. Many of those countries have pilots who believe it flew in so it will fly out.
Add to that operating in those countries is far more hazardous than in the USA. The USA has runways that are good (one DHC-6 I know of landed on a large runway that was serviced by Dash-8 and F-28 aircraft daily) and the pilot felt a hard jolt just after touchdown - when he climbed out he saw the nose gear was tilted back 30 degrees. Further inspection found a "bottomless" 2m/6ft dia sink hole in the runway that was not visible on approach - they closed the airport for months to fix it), navaids that work (and all the time - it is no fun being on long final approach in shit weather in pre GPS days and have the ground navaids you are depending on all fail because someone forgot to put fuel in the generator), good fuel, no one shooting at you, good weather forecasting, weather that seldom changes unpredictably (except in tornado alley), etc, etc, etc. A lot of third world countries have high temperatures with very high humidity and that is very conducive to airframe and engine icing at far higher temperatures than usually found in the US and which unqualified pilots are not trained to recognize or correct. Add to that many operators would rather carry cargo than fuel so there is insufficient fuel for a safe diversion. Now add to that one way runways where there is no possibility to do a go around and you start to get the picture.
I would expect the same aircraft maintained and operating under first world conditions to be no more troublesome than its contemporary equivalents.
