As the capitalist system lurches from one crisis to the next, old contradictions are re-emerging. Instability, polarisation and huge political shifts are taking place all over the world. As part of this process, unsolved national questions are erupting once more with renewed force around the globe - from Catalonia to Kurdistan to Ireland.
And it is not just on the national question that these giant shifts are taking place. The emergence of new political movements and formations, from Sanders to Corbyn to Podemos, reflect the impasse of the system and the fact that the masses - deprived of a party with a clear, revolutionary programme - are searching for a way out.
