The Ukraine crisis may well become a tipping point, sealing the fate of Eurasian alignments. The Western push to punish and isolate Russia is drawing Moscow closer to Beijing, which, tellingly, has taken a stance of benevolent neutrality towards the Kremlin's actions in Ukraine and its takeover of Crimea. One may suspect that, in exchange, Beijing would expect from Moscow the same kind of "benevolent neutrality" regarding its assertions in East Asia and the Western Pacific.
Wherever one stands on debates over the "proper" U.S. role in the world and contemporary geopolitical challenges, the antecedents are clear. After 1947 American national security--and foreign relations more broadly -- were no longer premised on a limited view of protecting the political and physical security of U.S. territory and citizens.
