This "support to Palestine" thing in its current form is unsustainable as it is neither helping stop the suffering of the Palestinians nor gaining BD anything.
Boycotting Israel has made them more defiant. What I would like to see happening is BD along with some other Muslim nations engaging with Israel, when a left leaning government takes power there, and negotiating a conditional recognition of Israel in exchange of a peaceful, non-discriminatory environment for Palestinians in whatever way suits Israel.
Once this is achieved, BD should heavily collaborate with Israel in the fields of science, technology and defence.
You think Jews are interested in peace?
They want nothing more than all Palestinians out of Palestine.
