NATO leaders are meeting in Brussels to decide whether to restore formal ties with Russia. Despite lingering tension, officials say the alliance’s foreign ministers are expected to end the freeze with Moscow, which followed last year’s war in the Caucasus.The US Secretary of State Hillary Clinton says Washington and Moscow are still going to have differences, with both sides standing their ground, but there is a hope of possible cooperation. NATO officials also stress that concerns remain over Russian action, but they have little choice but to work more closely on issues they have in common. However, alliance members are only too aware of the sensitivities that remain after Russia’s conflict with Georgia. Observers say Russia set the tone for a new start with the US and NATO this week by allowing cargo for American forces in Afghanistan to pass through its territory. Clinton is also due to outline progress in President Obama’s review of strategy in Afghanistan.
