this will be one of the questions that will have to be resolved when this is over however it comes to an end. it will come to an end. >> president zelenskyy said that tonight so far only been one day, 137 ukrainian soldiers have been killed since the invasion began. how much longer do you think ukraine can keep up this fight? they obviously don't have the capability to defeat a superpower like russia. >> well, i think they'll be able to put up a good fight for a while. they have an army today that's -- that they didn't have in 2014, for much more sophisticated, much for advanced, much more capable. but the overpowering weaponry and military and cyber capacity that russia has will overwhelm them, i'm afraid, unless something stops that, unless something intervenes.
