President Vladimir Putin is generally fond of blaming the West for the ills besetting Russia. This week though, he admitted in his State of the Nation speech that the roots of Russia’s sluggish economy may lie at home rather than abroad.  The government expects the economy to expand a measly 1.4 percent this year (less than half of the growth the US is likely to see) and long-term growth estimates have been trimmed to 2.5 percent a year.
