In March 1994, the Washington Agreement was signed, ending the Croat–Bosniak War, and providing Croatia with US military advisors from the Military Professional Resources Incorporated (MPRI). The US involvement reflected a new military strategy endorsed by Bill Clinton in February 1993. Because the UN arms embargo was still in place, the MPRI was hired ostensibly to prepare the HV for participation in the NATO Partnership for Peace programme. They trained HV officers and personnel for 14 weeks from January to April 1995. It has also been speculated in several sources,including "The New York Times" and various Serbian media reports, that the MPRI may have provided doctrinal advice, scenario planning and US government satellite intelligence to Croatia. MPRI, American and Croatian officials have denied such claims. In November 1994, the US unilaterally ended the arms embargo against Bosnia and Herzegovina, allowing the HV to supply itself as arms shipments flowed through Croatia.
