MADRID (AP) — NATO has declared Russia the “most significant and direct threat” to its members’ peace and security. That came as the military alliance met Wednesday to confront what NATO’s chief called the biggest security crisis since World War II. It also promised to “step up political and practical support” to Ukraine as it fights off Russia’s invasion. But Ukraine’s president chided NATO for not embracing his embattled country more fully and asked for more weapons to defeat Moscow’s forces. Russia’s invasion of its neighbor shattered Europe’s peace, drove NATO to pour troops and weapons into eastern Europe on a scale not seen since the Cold War, and was set to give the defense organization two new members in Sweden and Finland.
