While many thought that the eleven Central and Eastern European countries that exited communism and joined the European Union in the 2000s had made an irrevocable “civilizational choice,” Russia has sought to extend its influence into this unexpected new battleground. Though Russia has fewer tools of influence than in the lands in between, it has used energy politics, disinformation, support for extremist parties, business relations, and a variety of covert methods to cause Central and Eastern European governments and politicians to re-evaluate their allegiances. Central and Eastern European countries have experienced growing extremism, increasing polarization, and the rise of cynical power brokers who wish to accommodate Moscow, while also benefiting from EU ties and funds. Political leaders such as Viktor Orbán of Hungary have blazed this path, making gas and energy deals with Russia while undermining democratic politics at home and challenging the European Union from within.
