Why are NATO Articles 4 and 5 being mentioned after the blast in Poland?

Nearly a yr into Russia’s invasion of Ukraine, japanese European international locations stay fearful about their very own safety, whereas allies have warned Moscow that attacking NATO members would set off a broader, international battle.

The United States made a “sacred commitment” to Article 5 of NATO’s founding treaty, President Biden advised leaders of nations on the alliance’s japanese flank, who gathered Wednesday in Warsaw to debate considerations about Russian aggression. “We will defend literally every inch of NATO,” he stated.
