That Russia is helping the rebels is certainly believable. Yet, some of the NATO statements are so preposterous that everything NATO says is suspect. Let's take a look.
NATO: "We have seen columns of Russian equipment, primarily Russian tanks, Russian artillery, Russian air defence systems and Russian combat troops entering into Ukraine," General Philip Breedlove said on a trip to Bulgaria as fears mounted that a tenuous ceasefire would collapse.
Mish: Where can you hide a tank? More importantly, where can you hide "columns of equipment, primarily tanks"? If columns of tanks were heading from Russia into Ukraine, both US and NATO would have satellite images. So where the hell are the images?
Other statements by NATO appear more reasonable.
