u.s. troops to the region. what exactly would that mean? where are they expected to go? >> reporter: that's right, david. it's something he said earlier. we don't know the specifics but most likely you would have to think the baltic states, eastern europe, also potentially poland. critically, not here in ukraine, which isn't a member of nato. i think the eastern european states will be glad of that show of support, which is likely to come from the white house. but here in ukraine, president zelensky is likely to be less happy. he's worried by making these kind of moves, by talking repeatedly about war, it just creates panic and discontent here in ukraine. david? >> ian pannell we're grateful for your reporting all week long. thank you. now to the newly released images of the crash of a u.s. navy stealth fighter in the china sea. navy confirming video online shows this f 35 seconds before it crashed on to the deck of the u.s.s. carl vincent.
