samantha power today delivered stinging remarks implicating russia for its role in the separatist movement that's blamed for bringing down that plane. i want you to take a quick listen. >> on july 14th, separatists claimed credit for the downing of a ukrainian military cargo plane flying at 6,000 meters. on july 16th, they claimed credit for the downing of a ukrainian fighter jet. if indeed russian-backed separatists were behind this attack on a civilian airliner, they and their backers would have good reason to cover up evidence of their crime. >> and andrea, how might this tragedy impact the administration's ability to really convince europe to start standing up to the russians more on ukraine? >> if not now, when? so far the u.s. has been pretty much standing alone against vladimir putin. angela merkel has come along to a certain extent. certainly david cameron in the u.k. italy and france have resisted. so europe as a whole has not done big sanctions, big pressure.
