No government is ever going to tell the unvarnished truth to its population, particularly on matters of security nor should they unless they have a death wish (literally). As for Russia? If only!! China ditto. I'm afraid they perceive us in the West as dithering, ineffectual, and weak. Putin barely bothers to disguise his scorn for us! Our intervention in the first place was with hindsight a complete disaster, the road to hell etc comes to mind, but we are where we are , and no amount of handwringing or heart searching, or prosecuting this one or that, can alter what's happened, so all we can do is to try to do what we can with what we've got, hopefully for better (?!!) from the position we now find ourselves in.
