For at least the past five years, the government of Turkey has threatened to invade and annex Greek islands in the Aegean Sea.
The Turkish media continues to falsely and repeatedly claim that “152 Greek islands and islets in the Aegean belong to Turkey”. These islands, however, historically and legally… belong to Greece.
Since its inception in Arabia in the seventh century, Islam has spread throughout the world by means of the sword. According to the Islamic law, the world is divided into the “dar al-Islam” (territory of submission to Allah), which denotes regions where Islam prevails, and the “dar al-harb” (territory of war), which refers to non-Muslim lands, yet to be conquered.
Islamists believe that once Islamic colonialism and occupation has taken place, the land conquered is forever Islamic…. Islamic supremacists such as Erdogan believe that because Thessaloniki was once under the occupation of the Islamic Ottoman Empire, it is a Muslim land eternally and must be returned to its rightful owner.
Jerusalem… was also under Ottoman occupation for four centuries (1517-1917). The Jewish people, however, reversing that pattern of Islamic colonialism and imperialism, re-established their homeland, now Israel, in 1948. Islamic supremacists still have not healed from the perceived affront by Israel’s indigenous people to Islamic conquest.
Islamists therefore say they want to reconquer Jerusalem and the rest of Israel. According to doctrine, the only religion that should rule over these lands – or any lands, for that matter — is Islam. Christians and Jews could be only “dhimmis”, second-class, tolerated subjects of an Islamic state where they are only allowed to stay alive on sufferance by paying a high “protection” tax, the jizya.
Theologically, according to Islamic scriptures, Judaism and Christianity are merely distorted versions of Islam. In the Islamic view, originally there was only Islam, which the Jews and Christians later distorted into Judaism and Christianity. All history, in this mindset, is therefore originally Islamic history and all major figures of history such as Adam and Eve are therefore Muslim. All Biblical figures, according to Islam, such as Abraham, David, Moses, and Jesus are also Muslim. So, any place related to them, in that view, is Muslim territory.
Many others see these events as the Jews, who were the indigenous population of Canaan and Judea, having had their land “stolen” by the Ottomans, similarly to how the Turkish military invaded the northern part of the Republic of Cyprus in 1974, or how the Christian Byzantine (Eastern Roman) Empire was “stolen” by Ottoman Sultan Mehmed II and his troops on May 29, 1453 when they stormed Constantinople and triumphantly entered the Cathedral of the Hagia Sophia, after besieging the city for 55 days.
Many Islamists are therefore obsessed with conquering Israel, Spain and Portugal (al-Andalus), Greece, Cyprus and India for Allah – then the rest of the non-Muslim world.
