How dangerous is Barrack Obama's public underestimation of Putin?

Barrack Obama has made several contemptuous comments about the relative military, economic, political reach of Vladimir Putin. He has called him names. He has referred to Russia as merely a regional power, as if that isn't significant when the region is Europe - all so that he needn't say Mitt Romney was correct in his assessment that Russia is our primary geopolitical threat. Russia controls 40% of the natural gas that goes to Germany. Russia is seeking Naval facilities in Seychelles,Singapore,Vietnam,Nicaragua,Venezuela,Cuba and Argentina. Is Obama dangerous?
