Boycott, Divestment and Sanctions is a two-edged sword, bringing relief to starving Gazans, and bringing starvation to the occupier, argues Eric Walberg It was two years ago, on 27 December, that Israel launched its invasion of Gaza, carrying out 22 days of murder and mayhem, killing more than 1,400 and leaving 5,400 civilians crippled for life. Since then it has continued to besiege the 1.5 million Gazans, causing hundreds more unnecessary deaths. Its actions were deemed war crimes by the UN Goldstone Report. Israel remains unpunished, hiding behind the skirts of its US lobbyists, who put unremitting pressure on every single congressman, senator and the president to prevent any condemnation of its crimes. Its attempt to cow the Palestinians have failed. What Israel has succeeding in doing, however, is to confirm beyond a doubt, for millions around the world, its inhuman, racist agenda. The past two years have witnessed an awakening of world citizens to the plight of the brave Gazans. There have been more than a dozen convoys and flotillas, including Free Gaza boats that broke the siege five times, the Gaza Freedom March, the Gaza Freedom Flotilla -- to break the siege and bring Gazans emergency help. The latest caravan, the "Asia to Gaza Solidarity Caravan", representing 18 countries from the South, reached Turkey last week, the first aid convoy from the southern hemisphere, en route from India, Pakistan and Iran. It timed its peaceful "invasion" of Gaza to coincide with the anniversary of Israel's day of infamy. These efforts to bring relief to suffering Gazans are the positive part of the growing worldwide Boycott, Divestment and Sanctions (BDS) movement. But these positive efforts are fortified by equally important negative aims: to push Israel politically and economically to end the siege and make a just peace with the Palestinians. Politically it has given more and more governments legitimacy to move towards legitimising Palestine and even delegitimising an apartheid Israel. Important steps since Operation Cast Lead include: - Venezuela and Bolivia cutting diplomatic relations with Israel in 2009 after the invasion of Gaza, Nicaragua after the attack on the Freedom Flotilla in May 2010. - Bolivia, Brazil, Argentina and Uruguay recognising a "free and independent" Palestine with 1967 borders in 2010, with Paraguay to follow suit in the spring. - Norway and Britain upgrading their Palestinian Authority representative to consul, with the new year promising more European countries to follow suit. Israel besieges Gaza. BDS calls on the world to "besiege the siege", to starve Israel of its export and import markets and pressure it to make a just peace with captives. There were many victories on this economic front in 2010 too. Examples include: - Qatar cutting its trade relations with Israel. - Japan's MUJI abandoning plans to invest in Israel, facing immense pressure from citizens in Japan and South Korea. - Deals cancelled with Turkey, the UK, Egypt and the Gulf States. - A Turkish company demanding that Israeli companies sign a document condemning the Israeli massacre in Gaza to continue doing business. Israeli businessmen in Turkey now have to hide their identity. - European Union guidelines requiring supermarkets to mark the origin of produce on labels to allow consumers to distinguish between Palestinian, Israeli and settlement produce. - The decision by companies such as Multilock to close their West Bank businesses because of human rights organisation pressure. - The major Dutch pension fund PFZW disposing of the Israeli companies in its portfolio. Major Swedish and Norwegian investment funds sold their shares in all Israeli companies involved in building settlements and the apartheid wall. - The Chilean parliament's decision to adopt a boycott of Israeli products made in settlements. Dozens of BDS groups around the world, including in the US, are demonstrating in front of and inside stores selling Israeli products, urging management and customers to join the boycott. But the biggest impact on Israel, ironically, has come from the beleaguered Palestinians themselves. The Palestinian Authority has made it illegal for produced items from settlements to be sold in Palestinian stores. The West Bank market is worth around $200 million a year to Israeli businesses, with some settlement factories selling up to 30 per cent of their output to the Palestinian market. Seventeen factories in Mishor Adumim, a large industrial estate between East Jerusalem and Jericho, closed as a direct result of the boycott. As 22,000 Palestinians are employed by settlement businesses, the PA has established a $50 million fund to provide alternative employment and grants in an effort to both discourage Palestinians from working in the settlements and helping those who lose their jobs due to BDS successes. While Israel's economic media passes no judgement on Israel's political and moral failings, BDS is forcing it to wake up. The Marker warned about the growing boycott of Israeli high-tech companies by European and US companies which find they cannot invest in Israel for moral reasons. Nehemia Strassler, Israel's leading economic analyst, attacked the Israeli Minister of Industry, Trade and Labour, Eli Yishai, for calling on the Israeli military to "destroy one hundred homes in Gaza for every rocket that falls in Israel". He "doesn't even understand how the operation in Gaza hurts the economy. The horror sights on television and the words of politicians in Europe and Turkey change the behaviour of consumers, businessmen and potential investors. Many European consumers boycott Israeli products in practice. Intellectuals call for an economic war against us and to enforce an official and full consumer boycott." The world is changing before our eyes. Five years ago the anti-Israel movement was limited to the far left or Arabs and Muslims. Now the campaign is entering the mainstream as a red and green -- leftwing and Muslim -- alliance The boycott is an especially effective weapon against Israel because Israel is a small country, dependent on exports and imports. BDS was the key to ending the apartheid regime in South Africa and is fuelling world citizens with energy to the same to Israeli apartheid. And it is all thanks to Israel's Operation Cast Lead, letting the world watch Israel pound Gaza with bombs on live television, and its unapologetically racist government led by Prime Minister Binyamin Netanyahu and his Foreign Minister Avigdor Lieberman. Israeli-American artist Theordore Bikel, a recent convert to BDS, points to the legendary Pablo Casals, who refused to play in fascist Spain, saying "My cello is my weapon; I choose where I play, when I play, and before whom I play." There are many weapons mightier than the sword.
