How NATO factors into the Ukraine-Russia conflict

Putin’s military operation has prompted NATO allies, worried about further escalation, to issue sanctions meant to impact the Russian economy, bolster troops along the alliance’s Eastern flank and repeatedly warn that an attack on one NATO member is an attack on all.

In the wake of Russia’s attack on Ukraine, President Joe Biden announced that NATO will convene a summit Friday to “affirm our solidarity and to map out the next steps we will take to further strengthen all aspects of our NATO alliance.”

NATO membership is open to “any other European state in a position to further the principles of this Treaty and to contribute to the security of the North Atlantic area.”

NATO also has what it calls the Membership Action Plan. It helps aspiring members prepare for membership and meet key requirements by providing practical advice and targeted assistance.
