By December the article found its way to Mirzá Abu'l-Fazl in Beirut who wrote a fitting response to the attack on the Faith. Abu'l-Fazl signed it, and mailed it to 'Àbdu'l-Bahá, "so that He can, in his wisdom, decide what to do with it."

Àbdu'l-Bahá received the manuscript in New York on June 19, 1912. He had it translated and printed, and called it The Brilliant Proof. "Each one of you should have a copy," he told the Americans. "Read, memorize and reflect upon it. Then, when accusations and criticisms are advanced . . . you will be well armed." [239 Days Website]

After defeating the Ottoman army they confiscated on large scale the lands of the Arab peasants on which Italian settlements were established and large numbers of Italian settlers were brought in for the cultivation of cash products. The war cost Italy 1.3 billion lire, nearly a billion more than Prime Minister Giovanni Giolitti had estimated before the war. This ruined ten years of fiscal prudence.

This war is notable for the introduction of new military technologies including the use of the airplane for reconnaissance and bombing. It also included the first instance of an airplane being shot down by ground fire.

The Italians also used a wireless telegraph network established with the help of the Italian inventor Guglielmo Marconi.

This war is considered by historians as a precursor of the First World War. Members of the Balkan League, seeing how easily Italy defeated the Ottomans and motivated by incipient Balkan nationalism, attacked the Ottoman Empire in October 1912, starting the First Balkan War a few days before the end of the Italo-Turkish War.

The Battle of Benghazi was a preliminary to the fascist invasion of Ethiopia and Italy's ambitions to establish its own colonial empire. [Colonialism, Nationalism and Jewish Immigration to Palestine: Abdu´l-Baha's Viewpoints Regarding the Middle East by Kamran Ekbal p18]

The Brilliant Proof was first translated by Ali Kuli Khan and published by the Bahá'í News Service in Chicago in 1912 in which it said: "Written in response to published attacks on the Bahá'í Religion by the British clergyman Peter Z Easton" (1846-1915). [Collins7.15 p41]

Peter Easton (1846-1915) was a Presbyterian in the Synod of the Northeast in New York who had been stationed in Tabriz from 1873 to 1880. While 'Abdul'Bahá was in England Easton attempted to meet and challenge him. He made those around him uncomfortable and 'Abdu'l-Bahá withdrew him to a private conversation and then after which he left. Later he was able to have printed a polemic attack on the religion, Bahaism — A Warning, in the Evangelical Christendom newspaper of London (Sept.-Oct. 1911 edition.) It was published in the Appendix of The Brilliant Proof (p70-80) [Bahaipedia]

Lady Blomfield in her book The Chosen Highway (p183) described such a visit and the affect it had on 'Abdu'l-Bahá.

'Abdu'l-Bahá visited the home of Miss Ethel Jenner Rosenberg for a Unity meeting at White Lodge, 8 Sunnyside, Wimbledon (since demolished). [ABL44-45, In the Footsteps of the Master p.9, SYH40]
