Well, as far as autocracies, the Russians were in bed with Saddam, the Russians are now in bed with Iran who is striving to develop the Islamic Bomb and Russia is selling arms to Red China and Hugo Chavez.
The bottom line is that Russia should be casting its lot with the forces of liberty and freedom and yet, because of a pathological hatred and envy of the United States, Russia continues to cast its lot with authoritarianism and any fanatic regime that happens to hate America's guts.
Your argument is analogous to the assertion that there is a difference between the Imperial Germany of Kaiser Wilhelm and the Nazi Germany of Adolf Hitler.
My argument is that there is indeed a such difference but, in the end, that does not change the fact that both Imperial Germany and Nazi Germany considered the United States of America as their enemy.
My main focus is who considers the United States of America as their enemy.
I do not give a rat's ass as to their "Why"?
Actually the ones spreading nuke technology, as even the Lybians admitted, is Pakistan.
I suppose, you are from Poland (at least by the origin) or from West Ukraine?
