so resistance there that when you hear matthew chance say from his sources, ukrainian sources, there is fierce fighting, it is the u.s. view that there is fierce fighting. we do know and this has been a consistent assessment by the u.s. and nato that ukrainian forces are far outnumbered, by multiples in terms of personnel, armor, aircraft, air defense, et cetera. but that they're not giving up without a fight certainly at this stage. and that's important. that said, too, russia's broader ambitions here from the beginning as we have been talking about this war plan, even going way back to november, when we first began to report it, it was the u.s. view that russia's intentions were quite broad to take over perhaps the entire country and as this assault has begun, it remains the u.s. assessment that russia intends at least to control the eastern two-thirds of the country, really think kyiv going east towards those supposedly disputed regions in the east.
