Sorry apparently you posted after PHH and I didn't recognize that when I posted and moved on. Mine was in response to PHH's post.
However, in response to yours. For me, sure each regime gets a clean slate. But that doesn't erase what has happened before. It doesn't erase that you can easily look and see that Russia has changed little in the past 200 years or so. At least where their governments are concerned. Same shit, different day.
BUT, I will hold the USSR to what the USSR did and hold what Putin did to Putin. Rather than what the USSR did and hold it to Putin.
