No problem; and yes I think the best way to look at the Cold War is via the game theory approach of two powers battling each other. Each of them had ideologies that were integral to their actions, but not exclusively so, and they acted in ways contrary to those ideologies if it was deemed necessary in a realpolitik sense - which usually meant because the country in question was going to be influenced by the other player.
