Yes, I think that was a case of miscalculated Realpolitik, and I think they didn't realize until the phone call how much the Russians knew about what they had been up to there, but by then it was too late. In any case, it a created a problem that Putin HAD to resolve while the US only has to hover around and take advantage of any opportunities that may or may not present themselves.  So, strategically, it was a pretty ruthless and low-risk (for the West) move that would have impressed Saul Alinsky, if not Henry Kissinger.  I think Putin proved himself better player and politician than they expected to him to be.
