Just look at who he is friendly with:
- Hammas
- Hezbollah
- The Mahdi Army
- Sinn Fein/IRA
I haven't seen a shred of evidence that he's 'friendly' with any of these groups. This is what I have seen:
He is also a member of the Socialist Campaign Group, the Palestine Solidarity Campaign, Amnesty International, the Campaign for Nuclear Disarmament and the National Chair of the Stop the War Coalition.
