colleague dana here. you were talking about the nipa river. what is significant about this body of water when -- it is fairly broad. i mentioned one of the longest rivers in europe. how do you see that strategically? you were explaining that a few moments ago. >> it separates the country east and west obviously. rivers are always crucial because they are also boundaries and obstacles. and you can take advantage of it as well. so the nipa river is crucial and has a significant dam on it. that if you ever pulled the plug on that tens of thousands of people would be involved as casualties for sure. i don't foresee anything like that. putin is going about this the complete opposite of china. minimize civilian casualties. he knows the whole world is watching here.
