From an AP story by Lorne Cook headlined “Finland doubling NATO’s border with Russia in blow to Putin”:

BRUSSELS — The blue-and-white Finnish flag rises outside NATO headquarters Tuesday afternoon, making Finland a member and doubling Russia’s border with the world’s biggest security alliance.

The move is a strategic and political blow to President Vladimir Putin, who has long complained about NATO’s expansion toward Russia and partly used that as a justification for his country’s war with Ukraine.

“What we see is that President Putin went to war against Ukraine with a declared aim to get less NATO,” NATO Secretary-General Jens Stoltenberg said. “He’s getting the exact opposite.”
