Switzerland, Finland and Sweden are considering joining the US National Guard’s security partnership program. The move is seen as a further expansion of American military ties across Europe after Russia’s invasion of Ukraine.The chief of the National Guard, Gen. Dan Hokanson, said that US officials are in discussion with each country regarding the pact. The move is the latest indication of how Russia’s war has changed the security and geopolitical alignment of European nations. The Ukraine war has also led to each of these three nations to take steps that consider ending long-standing policies of military nonalignment.
