major escalation. in sign of that at this point. but there s real concern about what the next step of vladimir putin is, wolf. because it s clear to everyone that the ukrainian military is really under the worst of circumstances would be no match for the russian military, which is so much more powerful, so much more advanced. so the key as you correctly point out, according to u.s. officials, as well, keep the russian troops in crimea, but if they start moving eastward, towards where you are in kiev, that would escalate the situation dramatically. is there a real concern in kiev with the ukrainian government that the russian military might actually move toward the east? there is concern. basically everybody here you talk to has that concern. for them, that obviously is would be the ultimate act of declaration of war. they already see this as a declaration of war. but to move into eastern parts of ukraine.
