I don't think we've been duped. It's a question of whether Russia needs to be encouraged into a functional democracy or bullied into one. That's a legitimate question for debate, although it is obvious that we've taken the more cautious approach. If the former KGB, including Putin, are resolute in undercutting the US, and encouragement will never work, then we have to consider what would happen if we get aggressive.
Considering the deluded composition of the US Department of State, I'd be hard pressed to think that any effort at "duping" would be necessary. ;-)
