>> US armored vehicles rolling through the streets of a Latvian town. It's part of a show of force by NATO intended to deter Russian aggression in the region. But Washington is struggling to find partners for a Baltic force. Only Britain and Germany so far contributing to the planned unit.
In Lithuania, Reuters correspondent Robin Emmott says NATO Russian relations are at a low.>> That's a reflection of the crisis in Ukraine and Russia's annexation of Crimea in 2014. But also a sense in Moscow that NATO has broken what Moscow says was a promise not to expand up to Russia's borders in the east.
Here in Lithuania, there's a real sense of a need for a deterrent against Russia despite reassurances from Moscow that there is no such threat.>> Washington fears Moscow might take advantage of any signs of weakness in NATO. But some European members of the military alliance allow to do anything provocative.
Others say NATO should focus on the migrant crisis or the conflict in Syria. That might force the US to turn to Canada for help. Poland also covered by the new force. This week it hosted a major exercise by 20 NATO nations as part of preparations. Next week the alliance will formally commit 4,000 troops to the defense of the region.
That will leave many NATO members facing a difficult decision.
