One line from this BBC report http://www.bbc.co.uk/news/world-middle-east-38546740 struck me:
'The Palestinian leadership has blamed frustration rooted in decades of Israeli occupation.'
The institutionally anti Israel don't explain what the Palestinian leadership mean by occupation. It's the same as the anti Israel protesters mean when they chant "From the river to the sea..."
The Palestinian leadership, people and presumably the institutionally anti Israel BBC, see the whole of Israel as being on occupied land.
