Many people do already boycott Israeli products individually. It's everybodies decision. There is no obligation to buy Israeli products. An official boycott is a bit different. But if Israel goes still further with its oppressive politics, one day this reaction will have to be considered. Israel had the luck to profit from an enormous one-sided sympathy for a long time (I can speak of Switzerland), but at some point that is overstrained. By the way: The U.S. boycott Cuba and other countries, with an extremely poor justification. Israel on the other side has violated as many UN-Resolutions as no other state in the whole world. The world community has the right to express its discontent with this behaviour. This of course has to be proportionate. If the behaviour is constantly repeated, the usual reactions of the European countries, consisting in expressing "their deep concern etc.", seem to weak.
