Internationalism is at the heart of any genuine socialist politics.
As the present economic crisis makes clear, capitalism is a world system. Therefore it can only be effectively challenged by an international revolutionary movement.
The founders of the revolutionary socialist tradition played a leading role in such movements - Marx in the International Working Men's Association, and Lenin and Trotsky in the Communist International.
On a much more modest scale, Linksruck (Left Turn) in Germany and the british Socialist Workers Party belongs to the International Socialist Tendency. This is an international current of revolutionary socialist organisations which share the same political outlook and seek to help each other by exchanging experience and other forms of practical support.
Affiliated groups include the Socialist Workers Parties in Greece and Ireland, the International Socialist Organisations in Australia, and Zimbabwe, the International Socialists of South Korea, Canada, and Norway, and the Socialist Workers Organisation in New Zealand.
These links with socialists around the world are very important to us. But our internationalism is also put to the test in our daily practice, when we fight racism, organise against the Nazis, and mobilise opposition to the bullying imperialist foreign policies of Britain and the US.
