have been so emphatic in trying to stress this point is because germany has been a little bit reluctant in talking about some of the things that they would do if russia were to invade. so, we're talking about questions about sanctions. we are talking about the issue of sending weapons to ukraine. and also, of course, the nord stream 2 pipeline, which as this press conference showed, the u.s. and germany may not exactly be on the same page. and the added complication that i think is worth mentioning, too, is this is a new chancellor, new leader of germany biden was meeting with today, right? he doesn't have the same relationship with this chancellor that he did with the former-german chancellor, angela merkel. so, he made clear that one big mission that he had in having this bilat meeting today was simply to get to know his counterpart better. >> we will see what the results are in the coming days. mj lee, at the white house, following developments there. now, to moscow and our international diplomatic editor, nic robertson.
