Westerners as hostages

Putin is using westerners in the Ukrainian army as hostages, employing his sock puppet regime, the "Donetsk People's Republic", to threaten to kill them.

If it goes ahead with this, those responsible, from Putin on down, should face charges of murder. In the mean time, it would be appropriate to send commando teams to seize officials involved in this hostage plot, so as to offer to trade them for the hostages.
