The Soviet Union had become stagnant in an administrative and political sense. This can be explained as follows:

Administrative Stagnation:
1. Bureaucracy: The Soviet Union had a large bureaucratic system which was rigid and inflexible. This led to delays in decision-making and slowed down administrative processes.
2. Corruption: The bureaucracy was also plagued by corruption which undermined the effectiveness of the administrative machinery.
3. Lack of innovation: The Soviet Union relied heavily on centralized planning and did not encourage innovation. This led to a lack of creativity and hindered progress in various sectors.

Political Stagnation:
1. Single-party rule: The Communist Party was the only political party allowed in the Soviet Union. This led to a lack of political diversity and stifled dissent.
2. Repression: The Soviet Union was known for its political repression and human rights violations. This created a climate of fear and discouraged political activism.
3. Lack of democracy: The Soviet Union did not have free and fair elections. The political leadership was selected through a closed and opaque process.

Overall, the Soviet Union had become stagnant in both administrative and political spheres. This hindered progress and led to social and economic problems. The collapse of the Soviet Union in 1991 was, in part, due to this stagnation.
