A piece in today's NY Times (8/29/14, "With Gaza War, Movement to Boycott Israel Gains Momentum in Europe") says:
During the period around the Oslo Accords, in the early 1990s, when peace seemed close and economic cooperation between Israel and the new, interim Palestinian Authority was considered an important part of a future relationship built on mutual dependency and confidence, factories in occupied territory were praised.
That's the time frame for the construction of the Sodastream factory on West Bank land.
So Sodastream wasn't, then, seen as seizure. It was seen as progress.
I don't see any sign that die-hard proponents of the BDS (Boycott Divest Sanction) approach to Israel are capable of assimilating any such historical wrinkle.
They are doctrinaire. History annoys them.
