Russia and the USOs

I was reading about the Soviets having this year declassified reports on several encounters with USO's or unidentified submerged object. I wasn't aware of USO sightings for the longest time but have found it one of the more curious sides to the UFO and alien phenomenon. What the Soviets encountered were underwater objects moving at 230 knots, faster than the laws of physics would allow. Another account has several military divers on a training mission in Baikal when they encountered humanoid creatures dressed in silvery suits. Several of the divers perished when they moved to confront the creatures and several others were badly injured.

This is the kind of expert witness testimony of extraterrestrial intelligence that I think is difficult to discount. Why in the world would Russia, or any other government for that matter, release false information about contact with space aliens? What do they gain? If they have ulterior motives, what are they and why choose a story that so many will ridicule? Especially when its at their own military's expense. This report on USO's, given its source, is more evidence that the skeptics will find difficult to credibly refute.
