Speculative statements, an attempt to justify the creation of weapons of mass destruction as a response to an alleged threat from NATO. Consistent with the recurring pro-Kremlin narrative on NATO belligerence towards Russia.
NATO's missile defence system is defensive and not directed against Russia. Bilateral agreements between the US and host nations do not allow missile sites to be used for any purpose other than missile defence. NATO's exercises and military deployments in the Eastern Europe not directed against Russia – or any other country. Exercises are designed to ensure that NATO forces are trained, able to operate together and ready to respond to any threat from any direction. NATO has reached out to Russia consistently, transparently and publicly over the past 29 years.
The allegation about NATO's plans to wage a war against Russia was addressed on NATO's official website: "Any claims that NATO is preparing an attack on Russia are absurd." NATO is a defensive alliance and does not pose a threat to Russia. Its purpose is to protect its member states. Every country that joins NATO undertakes to uphold its principles and policies, and this includes the commitment that "the Alliance does not seek confrontation and poses no threat to Russia," as reaffirmed at the Brussels Summit.
