on his part. there's not only support for americans, there's support from europeans as well to do more in aiding ukraine and i'm just curious as to what point this becomes an arbitrary line of what aid is allowed and what aid isn't. are migs allowed -- not allowed but certain other weaponry is? and i'm asking because just this morning russia's deputy foreign minister threatened to attack western weapon shipments to ukraine. while the u.s. may be drawing a line here in differentiating between what that aid looks like, it doesn't appear that russia is. >> absolutely. putin doesn't need any reason to escalate, if he wants it. and they are acting aggressively and rhetoric is getting more and more aggressive because they -- this is nothing but weakness. president biden kept repeating that nato would not be involved in ukraine, but we would defend every inch of nato territory.
