conventional shortfalls. the russian army in its current form is not what it was during the halcyon days of the soviet union. it is a much lesser, smaller force than it was. so in the soviet remind -- the russian mind, a freudian slip there -- the way to compensate that is to consider the use of t tactical nuclear weapons. all of these factors, least for me, have sort of got the yellow flag up in terms of watching his continued behavior. >> yellow flag, not yet red flag, i'll note that. on that note, a viewer question, could the war cause a nuclear war? that's a question on people's minds now. >> it could. i'll just be straight up and blunt about it.
