the circumstances there in syria were different. i just say all that because i don't like our president taking things off the table. again, having said that i also do not want us to get actively involved. we should look at other opportunities. to get to your last question, we have to continue putting pressure on vladimir putin but he'll not stop if he sees that we are weak. we can find ways out for hem. diplomats offered all kinds of way out. he can hold to pieces of territory maybe that ukrainians will contemplate. there are many mechanisms. i don't believe he's completely cornered. he'll use his military fast to kill more ukrainians and get his way in a gruesome fashion. >> evelin, i take your point, the president should not take things off the table like no to a no-fly zone. he's not alone.
