In my opinion today is much safer for anyone to travel than 20 years ago. I am in industry where I deal with business travelers/tourist and they do not have any problem at all travelling around the world. This has to depend on from which country a traveler is flying from and the carrier he has selected to fly.
If there are dangers for travelers to make a trip to any destination the embassy will immediately notify the travelers and it would be a NO GO destination and again this depends on the airline itself.
Everything seems to be peaceful for anyone wishing to take a trip to any part of the world. We cannot predict the future what will happen in the next few years.
