did you ever think as a historian we would see russia reemerge on the world stage like this? >> you know, once the soviet union broke up in 1991, we were the only super power for a while, at least we thought we were the only one and we started doing nato enlargement and poland game part of nato. putin is an old kgb type with keen memory, and he's trying to reestablish empire, reclaim at least the soul of the ukraine and control the oil in the middle east of iran and syria. russia is good at two things, oil and nuclear weapons. they don't really have the same type of air force we have or navy, but the nuclear weapons are quite a deterrent.
