Their basis for saying that they are at war is that the west and the islam is at war. Are you going to grant them the right to do this? To declare this war for and on all the people in the west and all muslims - alongside the fundies and the states?
They have as much rıght to declare themselves at war wıth the Brıtısh state as, for example, Che Guevara had to declare hımself at war wıth the Cuban state.
Indeed you could argue that they had far more rıght, sınce they are Brıtısh whıle Guevara was not Cuban (or Congolese, Algerıan or Bolıvıan come to that).
So would you call the landıng of the Granma a crımınal act?
