Found this interesting in light of the uproar over the recent NATO summit.
Just became aware (thanks to Austin Bay at Strategy Page) that in
May, the Swedish and Finnish Defence Ministers came to Washington and
signed a Trilateral Agreement with the United States regarding the
national security relationship between the three countries, in response
to what is seen as a growing threat from Russia. Neither country is a
member of NATO.
While the US has had informal bilateral agreements
in the past with each country this is the first time America has joined
in a tripartite agreement. Among the items agreed to was a joint
military exercise in 2021 to be hosted by Finland.
Announcing the agreement, Secretary of Defence Mattis praised the two European nations for “providing
a steady anchor of stability in a region more tense as a result of
Russia’s unfortunate, unproductive and destabilizing choices from the
Ukraine to Syria.”
Here is an article from a Finnish paper on the agreement.
And one from a US publication.
