I did actually point out our past failings, but Russia does it hell of a lot more consistantly than us! Sell sell sell, without thinking of the consequences of their actions... sounds like Putinesque politics to me "I know, to solve a seige on a school we'll ram the walls down with Tanks and use gas!!" Yes... very subtle that!
Not an example of arms sales, but of one where they've not thought their actions through, with very costly consequences! Of course they didn't take the blame for their mistakes in that terrible episode, same with the theatre seige. They administered an "experimental" nerve agent unevenly without a working antidote... very clever! Killed more people than the terrorists did!
