'All of the letter’s signatories are people of distinction; many of them are personal friends. But we believe that this debate will be deficient if it does not incorporate the perspective of U.S. allies in Central and East-Central Europe.

While we share many of their concerns, we also feel compelled to present our own perspective.'
Just have a read this tremendous opinion including authors' reccomendations point-by-point.
