Most people don't want to travel to countries with riots.
I was in Greece for 10 days in 1977, and I loved it. Now, if we were going to spend $10,000 on a dream of our life trip, Greece, Egypt, Turkey, etc. would not be on our list. Come to think of it, there are very few places that would be worth spending that amount of money to see, even aside from the safety factor.
Good Luck Greece. Be good friends, and try not to take us down with you.
Taiwan, Japan and China!
See the world before you leave it!
