Imagine how he'll be tickled as NATO leaders fall all over themselves trying to find ways to refer to his sending Russian troops into a neighboring country without actually calling it an invasion.David Rothkopf: Vladimir Putin will be entertained watching the NATO SummitNATO's rhetoric has been its only weapon against Russian aggressionNATO is not designed to respond to Putin's style of incremental takeoversNATO, U.S. absorbed with fighting Islamic extremism and solving domestic issues
