"...Russia is again on the march in the Arctic and building new nuclear icebreakers.
It is part of a push to firm Moscow's hand in the High North as it vies for dominance with traditional rivals Canada, the United States, and Norway as well as newcomer China.
Interviews with officials and military analysts and reviews of government documents show Russia's build-up is the biggest since the 1991 Soviet fall and will, in some areas, give Moscow more military capabilities than the Soviet Union once had.
The expansion has far-reaching financial and geopolitical ramifications. The Arctic is estimated to hold more hydrocarbon reserves than Saudi Arabia and Moscow is putting down a serious military marker."
