are it could cost as many as 100,000 civilian casualties and up to five million refugees. >> we now live in a world where you can just go in and take a country because you claim it, well, we have entered a very dangerous period in human history once again. and there's another fear that unchecked russian aggression could encourage others, namely china to do the same. >> our adversaries are watching if putin can go into ukraine with no resistance, certainly xi will take taiwan. >> now there is obviously a presence in eastern europe but the u.s. military is not sending troops directly into ukraine, correct? >> that's correct. the president has said explicitly u.s. forces are not going into ukraine to fight russia. what he is doing is sending forces out to backup u.s. allies including about 2000 troops to poland, a thousand to romania and more on standby if needed if putin makes a move. now the u.s. really wants to confront russia diplomatically, not militarily.
