My dilemma: you are a nice guy and so is Velund.
In response to your post, let me just say that at least Russia is doing what's best for Russia, the details of annexing Crimea aside. I only wish our idiots in the DC followed the same rule.
Russia didn't poison a Brit, if they did it at all. Under the worst case scenario, they (a big if) executed a Russian who was hostile to Russia and couldn't just enjoy life in a new country. We, the US, execute terrorists left and right from the Predators or with cruise missiles - as well as those near them at the time of explosion. You know, collateral damage. Obama was especially good at it.
Finally, the US shot down an Iranian plane full of passengers. So, the Russians do not have a monopoly on such behavior. BTW, we admitted shooting it down. They did not.
Things are not as black and white as we would like them.
If you take the head count of all the dead that the Western "democracies" caused since the end of WW2, the Soviets and, later, Russia are not even remotely close to that number. Yet, the West is nice, Russia bad. Go figure this one out.
