ato’s leaders gather in Washington on July 9th-11th to celebrate “the greatest military alliance in the history of the world”, as President Joe Biden calls it.
He is right. nato has helped keep the peace in Europe for 75 years, a stunning achievement after the continent’s centuries of war.
Its “Article 5” guarantee—that an attack on one member is an attack on all—has deterred first the Soviet Union and then Russia. nato has also been a forum for resolving tensions between its members.
Small wonder nervous nations clamour to become part of it. Membership has risen from 12 in 1949 to 32 now, with Sweden joining in April and Finland last year.
