Acting Ukrainian President Turchynov is referred to as "acting" because he was never actually elected by anyone other than the US ambassador.
That "presidential" schtick is just an act!
That's probably why the troops theoretically under his control seem to have a hard time taking him seriously. Here's President Turchynov quoted at Kyivpost.com today;
I will be frank: Today, security forces are unable to quickly take the situation in the Donetsk and Luhansk regions under control," said Turchynov.
He said that the situation has detriorated to the point that Kyiv cannont control its own troops. In recent weeks, numerous Ukrainian military and security personnel have defected, turning over their arms to pro-Russian insurgents and joining the separatist movment.
""The security bodies ... are unable to carry out their duties of protecting citizens. They are helpless in those matters. Moreover, some of those units are either helping or cooperating with terrorist organizations," said the interim President.
They have at least enough pride and professionalism and loyalty to Ukraine to refuse orders from a US-installed stooge.
