Here's a terrific piece by Seumas Milne on what the Empire really fears the most- and it's not Islamic terror.
The problem with European communism was not that it was unsuccessful, but that it was too successful. Undermining communist/leftist regimes has been the number one priority in Washington since the late 1940s- it's why the mujahadin was funded in the 1980s- and why the US sided with radical Islamists in the Balkans in the 1990s. It's also why sanctions are imposed on both Cuba and Belarus. Belarus is a particular irritant for the US- it's the only former Soviet Republic which has actually risen in the UN Human Development Index since 1991. It's done so by following a completely different path to the one prescribed by the US/The IMF and the World Bank. The success of Belarus is living proof that there is an alternative to the current neo-liberal orthodoxy. Which is why, for The Empire and its emissaries, 'regime change' in Minsk is now such an urgent priority.
