The 2006 Riga summit or the 19th NATO Summit was a NATO summit held in the Olympic Sports Centre, Riga, Latvia from 28 to 29 November 2006. The most important topics discussed were the War in Afghanistan and the future role and borders of the alliance. Further, the summit focused on the alliance's continued transformation, taking stock of what has been accomplished since the 2002 Prague Summit. NATO also committed itself to extending further membership invitations in the upcoming 2008 Bucharest Summit. This summit was the first NATO summit held on the territory of the formerly Soviet-occupied Baltic states. Security measures The summit was held in the Olympic Sports Centre, Riga. Roads in the center of Riga were closed down and parking was not allowed at the airport or at several roads, out of fear of car bombs. About 9000 Latvian police officers and soldiers took care of the Summit's security, while more than 450 other airmen from seven European NATO countries were called upon to ensure a no-fly zone above the summit in an operation called Operation Peaceful Summit. This enhanced ongoing Baltic Air Policing activities with additional aircraft, communications and maintenance support. Summit All agreements were not actually made in the North Atlantic Council meeting, but in fact, it was made in the Istanbul Summit, 2003, except for the signing of the missile defense contract which happened on 28 November. The Council meeting was held on 29 November. Main topics While the tensions between NATO members from the build-up to the invasion of Iraq had dissipated, the NATO summit, and the months preceding the summit, were marked by divisions between the United States and the United Kingdom on the one side and France, Germany, Italy and Spain on the other. Two rifts existed, one about the military contributions to the war in Afghanistan, and the other concerning whether or not NATO should assume a more global role. War in Afghanistan Before and during the summit US president George W. Bush, British prime minister Tony Blair, Canadian prime minister Stephen Harper and Dutch Prime Minister Jan Peter Balkenende made a plea to European NATO members to make more troops available for deployment in Afghanistan, remove the national caveats (i.e. national restrictions on how, when and where forces can be used) and start sending its troops into the conflict-ridden south of the country.
