Is it true Russian language does not have variations?

Although Russian is spoken in vast areas, it does not have many variations or dialects.

1. Is it true that Russian accent is uniform almost everywhere?
Do people from Moscow and Vladibostok have the same accent?

2. Do people from Former Soviet Union(such as Kazakhstan, Uzbekistan and Ukraine) speakRussian with the very same neutral accent?

3. German has many dialects and variations even if it is spoken only in Germany, Austria and Switzerland. Providing #1 and #2 are true, how come Russian is so uniform in such a vast land?

1. No.

2. No.

3. It isn't.

1. Among native speakers, yes it is basically uniform.

2. If Russian is not their primary language, they tend to have accents.

3. F*cked if I know.

there are many nations in Russia and though all people living in Russia considered to be Russian according to country they live in, nearly all the suburbs of Russia consist of different nations who have their own mother tongue, their own traditions and just central part of russia consists of people for whom Russian is native. but all other nations for whom Russian is not native are good at Russian, speak it almost fluently 'coz its official language

1. Yes.
Actually there are some local features in every region, but they are very insignificant and mostly concern [a] and [o] pronunciation or intonation patterns. Generally the language is the same throughout the country.

But Russia is a multinational country and there are many immigrants here. People whose native language isn't Russian often have strong accents. It doesn't mean they speak any dialect of Russian; it means they just don't know the language properly.

2. No. See above.

3. The explanation is in history.
Before the unification in 1871, Germany was just a number of different state with diffent laws and traditions. That's why their language has so many difefrent dialects. On the contrary, USSR was a centralized state and the life of every region was strictly controlled by the single government. Every child of the country was tought by the same ABC book. Moreover, people were moving in very often. For example, every graduate was offered a job by the state and the jobplace was in a different region in most cases. Hence the whole population was stirred.
