The Russians have never not been a friend of America. They have always supported regimes which fought against the United States. Have you seen any changes? The only change I saw is that the Russian began to allow themselves to interfere in the internal Affairs of America. Before, I don't remember.
Russians have supported secular regimes instead of Islamic fiefdoms. Look at Syria. Bashar al Assad is the last remaining secular ruler in the entire Middle East. Russia is right in supporting him.
