WASHINGTON (Reuters/AFP) - US President Barack Obama said on Tuesday "all of us" want an effective exit strategy from Afghanistan in which Afghan authorities are able to take more responsibilities. Obama made the comment after talks at the White House with Netherlands Prime Minister Jan Peter Balkenende that centred on the current situation in Afghanistan as well as the global economy and climate change. "All of us want to see an effective exit strategy where increasingly the Afghan army, Afghan police, Afghan courts, Afghan government are taking more responsibility for their own security," Obama said. Around 4,000 US Marines and hundreds of NATO and Afghan forces are taking part in an offensive in various parts of Helmand province against the Taliban, the biggest by foreign troops since they ousted the group in 2001. "If we can get through a successful election in September and we continue to apply the training approach to the Afghan security forces and we combine that with a much more effective approach to economic development inside Afghanistan, then my hope is that we will be able to begin transitioning into a different phase in Afghanistan," Obama said. The President said he hoped the Netherlands would continue its participation in the Nato-led forces fighting to defeat the resurgent Taliban. "I recognise that participation in the coalition in Afghanistan can be controversial in the Netherlands," Obama said. "What I shared with the prime minister was the hope that even after next summer that there is the ability for the Dutch to continue to apply the leadership and the experience that they've been able to accumulate over these past years." About 2,000 Dutch soldiers are deployed in Afghanistan, mostly in Uruzgan, as part of a Nato-led International Security Assistance Force (Isaf). Nineteen Dutch soldiers have been killed in Afghanistan since 2006.
