@oralloy,

The problem with your conclusion is that anybody can access most countries in this world. Even China, Russia, and Cuba. I've visited all three countries. I have friends in Russia and Cuba. I even know Hiroshi Robaina who owns one of the largest tobacco farms in Cuba. I also know Cesar who works at the Nacional Hotel. It's the hotel where movie stars and VIP's stayed in the 1950's. I wouldn't want to visit some countries that are unsafe, although we are allowed to visit. I visited Egypt not long after some German tourists were killed many decades ago. When I made my plans to visit Egypt, my family and friends told me I was crazy to visit, but it was the safest place to visit. We had police escorts from and to the airport. Another benefit was that the famous tourist sites were practically empty, and we had them all to ourselves when normally there would be hundreds, if not thousands of visitors. I took my sister with me on that trip, and we also visited Jordan.
