Analysis: Jonathan Marcus, BBC diplomatic correspondent
Nato sees its actions as entirely defensive - but this is not the way they will be seen in Moscow.

Nato's wider actions - it also plans to open a training centre in Georgia and support for the reform of Ukraine's military - all ring alarm bells in Moscow.
Tensions could get worse still if the US or other Nato allies move to arm the Ukrainian military.
This is not a Nato issue as such but something for national governments, and everyone is watching the course of the evolving debate within the Obama administration.
