For practical purposes, we have organized Europe into two categories which are coincident with the geopolitical regions of Western Europe and Eastern Europe. The Eastern Europe's territory, which reaches the Ural mountains on the East, hosts, nowadays, twenty five countries, many of them surged after the shattering of the Soviet Union and the former Yugoslav Republic.

This category lists papers about countries in the region, such as Russia, Ukraine, Georgia, Azerbaijan, Armenia, the Baltic States, Poland, the Czech Republic, Romania, the Balkan States, and Turkey. It also list articles about the entire region. The case of Russia case is very special, given its territory is largely deployed between Europe and Asia, it has got the status of transcontinental state. Anyway, we decided to gather in this category all articles about it

Russia is today, together with the United States, one of the two states with largest WMD arsenals, most of them developed during the Cold War. Such arsenals have been inherited by Russia, as well as the status as a permanent member of the UN Security Council. Although arsenals got considerably reduced over the time the state already keeps a big quantity of nuclear, bio and chem weapons, and of their delivery systems.

After the USSR's fall, Ukraine, turned out a country with the third nuclear arsenal worldwide, but it decided to transfer them to Russia. Today, it does not keep any WMD or delivery system.
