Chamber musicians may not be aware that there is a global movement on right now to drive Israel into breaking down it’s apartheid policies. This movement is utilizing the technique that helped end apartheid in South Africa over two decades ago. This movement is called boycott, divest and sanctions. Known as “BDS,” it started in 2005 by the PACBI (see www.pacbi.org) – The Palestinian Call for the Academic and Cultural Boycott of Israel – in the occupied West Bank.
That BDS is feared by the apartheid regime of Israel is well known, and all attempts are made to silence the many recent BDS success stories. Israel seeks to shield it’s citizens from the deepening pariah status of their nation.
That Israel is indeed an apartheid nation is still under debate in some circles, and it is totally denied by others. But documentation has proven that Israel is indeed committing the crime of apartheid 
These photos of the apartheid wall are usually a surprise to most people in the west, this is the ugly face of apartheid that has created a vast ghetto out of what little land Israel has not yet confiscated from the Palestinians.
 See references below for documentation on apartheid in Israel:
Israel commits crime of apartheid: "Inhumane acts of a character similar to other crimes against humanity "committed in the context of an institutionalized regime of systematic oppression and domination by one racial group over any other racial group or groups and committed with the intention of maintaining that regime."
