u.s.? >> i think the options are very limited for us. i think in this particular case he is there, he has 120,000, 130,000 troops there. it is under his, you know, aegis as such, the neighbors, he can invade quickly. then the question becomes what is the price he is going to pay on the ground? would the ukrainians fight? would there be blood letting on the part of the russian forces? would they be sending them home in coffins, etcetera? that is one element where the ukrainian fighters would fight. then there would possibly insurgency against the russian personnel and then he's got to contend with will we in fact put more and more troops into the nato countries near him? what is his response going to be? as he has been suggesting put troops in cuba or venezuela? this is something we have to be very careful about and i praise the president for taking measured responses. i know he is being pushed to do.
