I do not believe there is today a substantial risk that Germany will become a powerful nationalistic dictatorship as it did in 1933. My reasons for this is that there are preventative apparatus built into the Federal Republic of Germany's government and that the German people today have more faith in democracy that the did post 1933.
First lets take a look at built-in preventative measures I talk about. Germany's government is one of federalism. According to Roskin (p. 197), federalism is defined as a system of government where its components have considerable autonomy. In Germany's case these autonomous components are called Lander, similar to a U.S. state. The inherent struggle of powers between the Lander and the National government prevents the central government from becoming powerful. Another apparatus of the German government that helps prevent that centralization of power is the its" Supreme Court (Roskin, P. 205). Much like the U.S. Supreme Court the German Supreme Court is independent from other branches of government, makes sure that all statues are pursuant to the Basic Law that protects civil liberties, and unlike their U.S. counterpart are able to declare dangerous political parties illegal. The last two apparatuses that I will point out is Germany's two-plus party system and its" split electoral system. In Germany's two-plus party system, the government is formed by coalition between a large and small political party. Its split electoral system gives voters two votes; one for a district representative (who is supposed to support the interest of its constituents) and another to determine the number of seats a party will hold. Together, not only do these systems make government coalitions stable it also prevents any one party from gaining too much power.
My second argument in opposition to the risk of Germany becoming a powerful nationalistic dictatorship is the German faith in democracy.
