Let’s be traditional first: The main purpose of the transatlantic relationship in the 21st century will look familiar to those who have studied its history since 1949: To prevent a situation from emerging in which Europeans feel they need to call Moscow first, instead of Washington, in questions of international politics. Add Beijing to the equation, and you get an idea of how daunting the task will be.
Transatlantic relations are the permanent suspension of conventional geopolitics for the purpose of limiting other powers’ influence over a Europe they could otherwise own. Look at the map, and you understand that, based on size, wealth, population and location, it is Russia that should dominate Western and Central Europe. It does not do so because America’s presence and promise of security to Europe creates an artificial barrier that Moscow has been unable to overcome since the end of World War II. With NATO and EU expansion, this barrier has moved eastward by a few hundred kilometers, and this is where, if all goes well, it will remain for some time to come.
