I think protest and actions have to be organised against the Israelis and their backers. There needs to be a concerted high profile campaign to raise awareness of the people in this country.
In my view the European culture carries a very heavy responsibility for the creation of Israel... it is a product of both British and Stalin's anti- Semitism, but the British never faced their own complicity in its construction.
This sympathy is not translated into force against the British government because it is not like the anti- apartheid movement which had a high profile here and Mandela is a more engaging figure than Yasser Arafat.
