Central Europe — Poland, the Czech Republic, Slovakia, Hungary, Romania and Bulgaria — is a region caught between Western Europe and a rising Russia, and it is of vital interest to the United States. Three major geopolitical trends are leading to shifts in the region: growing pressure on the European Union and within NATO, Russia's increasing influence in Europe, and a geopolitical battle between Russia and the United States. One of the most important countries within Central Europe is Romania. Located in the southeastern corner of Europe, and a member of both the European Union and NATO, Romania is a strategic country of 22 million people on the borders of several major powers. It therefore provides a case study of the three major unfolding trends shaping the region. The effects these trends have on Romania are important indicators of how the trends will progress in the wider region in the coming months and years.

At the heart of NATO's challenges are the diverging interests of its members, which have evolved significantly since the Cold War era. These growing differences were made evident in NATO's Strategic Concept. The largest divergence is between Western European countries that want to work with the Russians, like France and Germany, and countries that fear Moscow. Romania is firmly in the latter camp; it has a contentious relationship with Russia over Moldova, and particularly over Russia's military presence in the breakaway Moldovan region of Transdniestria. Bucharest is also concerned with Russia's military buildup in the Black Sea. In this context, NATO has been showing early signs of splitting into regional blocs. One of these emerging blocs is the Visegrad Group (V4), which recently declared its intention to form a battlegroup by 2016. Though the V4 does not currently include Romania, the country would be a logical extension of this nascent group in terms of needs and interests. Showing Romania's concern over the developments and prospects for both the EU and NATO, Romanian President Traian Basescu recently stated that European countries must cede their sovereignty and form a "United States of Europe" if Europe is to remain an economic and military power. Basescu added that the "European Union's future as a political structure is uncertain unless proper decisions regarding its functioning are taken." Basescu's views reflect Romania's attitude toward the European Union's future — an exasperation that leads to greater chances for regionalization. It is not that Romania and other Central European countries want regionalization, but it is one option, given the divergence between Central Europe's and Western Europe's interests.

While the BMD system officially is supposed to counter threats from rogue states like Iran and North Korea, Russia knows these systems would come with an increased U.S. troop presence. Therefore, it adamantly opposes such a system being set up in Central Europe. Romania is a crucial part of this system, with ground-based SM-3 interceptors slated to be delivered to Romania in 2015. However, these BMD plans are long term and will be shaped by external factors, such as the United States' ability to extricate itself from the Middle East and Russia's success in resurging into its near abroad. Indeed, the United States has already altered its BMD plans due to Russian resistance, which has shown the Central Europeans that such U.S. plans and security commitments are not set in stone. Given that Romania already has a tangible U.S. security presence and commitment, it is in a different position from the other Central European countries. However, Bucharest is still deeply concerned about Russia, which is gaining power, making inroads with Western European countries and using its relationships with Western European powers to undermine the Central Europeans' confidence. All of these trends indicate uncertainty ahead for Romania, particularly since Bucharest has little control over these developments. The United States, Russia and the Western Europeans are shaping these trends, and Romania will be key to watch to gauge how Central Europe will be affected.
