The US embassy in Paris advised Washington to start a military-style trade war against any European Union country which opposed genetically modified (GM) crops, newly released WikiLeaks cables show. In response to moves by France to ban a Monsanto GM corn variety in late 2007, the ambassador, Craig Stapleton, a friend and business partner of former US president George Bush, asked Washington to penalise the EU and particularly countries which did not support the use of GM crops. Moving to retaliation will make clear that the current path has real costs to EU interests and could help strengthen European pro-biotech voices," said Stapleton, who with Bush co-owned the St Louis-based Texas Rangers baseball team in the 1990s [and is married to Dorothy Walker, a first cousin of former U.S. president George H.W. Bush]. In other newly released cables, US diplomats around the world are found to have pushed GM crops as a strategic government and commercial imperative. In addition, the cables show US diplomats working directly for GM companies such as Monsanto. It also emerges that Spain and the US have worked closely together to persuade the EU not to strengthen biotechnology laws. In one cable, the embassy in Madrid writes: "If Spain falls, the rest of Europe will follow." The cables show that not only did the Spanish government ask the US to keep pressure on Brussels but that the US knew in advance how Spain would vote, even before the Spanish biotech commission had reported.
