I’d say it’s somewhat safer, on the whole, as the number of terrorist attacks worldwide has dropped. What I believe is arguable is how long after January 20 that will last.
I was including developments with other countries, Russia, Iran, Venezuela, Inda-Pakistan, Indonesia. Add the growth of Islam in western countries. I think the cultural and demographic developments in Europe and a lesser extent the US are just as dangerous as terrorists. Mix in Chinese influence everywhere, the growth of their space and military programs.
Don't know what Bush could have done about some of them, but I think the world is more dangerous then it was 8 years ago.
