Brief Explanations:
La expansión de la OTAN en la década de 1990 fue vista como una amenaza por la Unión Soviética. Esto llevó a la creación de una alianza opuesta en Europa Oriental, la Alianza del Tratado de Varsovia. Las otras opciones no son correctas: los países miembros de la OTAN no prohibieron las armas nucleares, ni formaron un solo gobierno, y la expansión de la OTAN no causó disturbios civiles en Europa Oriental directamente por este motivo.
