I think you're detecting a false pattern there. Russians generally do kick ass in Mathematics. In the West, Mathematics was held back by the Bourbaki fanatics, while in Russia they were never afraid of marrying the pure with the applied, the beautiful with the useful.

There may be a lot of Linear Algebra books translated from Russian, but there are also a lot of other books by Arnold, Kolmogorov, Fomin, Gelfand, etc that were also translated from Russian and that were not on Linear Algebra.
