To understand how unstable the Kremlin and Russia are and whether Russian President Vladimir Putin could face a challenge to his hold on power, we must return to the difficult study of Kremlinology. As in the Soviet period, the Kremlin's instability and challenges are not public or overt. Piecing together events, rumors and media stories, however, can give indications about significant changes on the horizon. Stratfor is beginning to see these pieces fall into place. This is not to say that the Russian government is on the verge of collapse, or that Putin will soon fall from his position as president. However, it does indicate that a dangerous struggle is underway that could bring about a significant change in the country's power structure. Of all the battles currently going on inside the Kremlin, one has risen high enough to cause noticeable instability.
