An interesting development but from a Christian standpoint it's irrelevant. We're talking about two godless nations agreeing on some measure of peace and nothing more. The big question is how Iran will respond.
Actually its extremely relevant because a war in the Middle East endangers millions of Christians. Many Middle Eastern Christians are survivors of ISIS, or the Turkish genocide of 1915 and the ethnic cleansing that resulted from the Greco-Turkish population exchange in the 1920s and the Great Fire of Smyrna, and other historic persecutions dating back to the Fatimid Caliphate, including in Egypt 10 million Coptic Orthodox, 350,000 Alexandrian Greek Orthodox, roughly 300,000 other Christians; 1.6 million Maronite Catholics, Antiochian Orthodox and other Christians in Lebanon, 370,000 Christians in Iran, mostly Armenians and Assyrians; roughly 300,000 Christians in Turkey (and various historic landmarks of the Armenians, and the ancient center of the Syriac Orthodox Church in Tur Abdin, near the borders with Iran and Syria); 1.2 million Christians in Syria (possibly less due to the civil war and Iraq), chiefly Antiochian Orthodox, Syriac Orthodox, Melkite Greek Catholic and Syriac Catholic, with some Assyrians and Protestants; somewhere between 500,000 and a milion Iraqi Christians, mainly Syriac Orthodox, Chaldean Catholics, and Assyrians** due to ISIL’s conquest of the Nineveh Plains, the historic homeland of Assyrian Christians, and persecution of Christians by militias and insurgents after the Iraq War; about 230,000 Christians in Israel and Palestine, including Melkite Greek Catholics, predominantly Arab Christians in the Greek Orthodox Patriarchate of Jerusalem, Armenian Orthodox and Syriac Orthodox, as well as virtually every other denomination in existence in at least small quantities due to the importance of the Holy Land to Christians, and finally 12.8% of the 8.8 million people living in the UAE are Christians of all denominations present in the Middle East, and many expatriate Americans and Europeans who attend churches that reflect their nationality (mainly Protestant and non-denominational).
The Christians of the Middle East in many cases represent the oldest continuing Christian churches in the world, with some worship traditions dating back to the 3rd and 4th century. The churches in the Middle East were in many cases founded by the Apostles (the Antiochian and Melkite Greek Catholic churches can trace their origin to St. Peter, who led the Christians in Antioch* before moving to Rome, the Coptic Orthodox, Coptic Catholic and Greek Orthodox Patriarchate of Alexandria were founded by St. Mark the Evangelist, and the Syriac Orthodox Church, the Syriac Catholic and Chaldean Catholic churches, and the Assyrian Church of the East and Ancient Church of the East, trace their origin to St. Thomas the Apostle. Many other churches in Lebanon, Turkey and Cyprus were founded by St. Paul and St. John. The church in Jerusalem was re-established when the city was restored under Empress Helena following the Roman Empire becoming the third Christian country after the city state of Edessa and the Kingdom of Armenia in 314.
So, the Muslim rule of these countries means we have to pray for the Christians of these lands, given the history of persecution following the conquest of the Byzantine Empire and most other Christian states in the region (Armenia, South Sudan and Ethiopia are the only Christian majority countries in the larger region, and Lebanon is the only country where Christians represent a substantial portion of the country and have real political power). Brokering peace between Israel and the Arabic lands is of vital importance so that Christians aren’t caught in the crossfire.
*Antioch was also home to St. Ignatius the Martyr, a disciple of St. John the Apostle, who was bishop of Antioch until the Romans fed him to lions; his epistles to the churches he wrote en route to Rome to be killed, urging the Christians to not try to rescue him but to allow him to die for Christ, are considered by many to be the finest Ante Nicene Christian literature, and indeed, these epistles along with 1 Clement and the Epistle of Polycarp were considered for inclusion in the New Testament before the decision was taken to limit the New Testament to the first generation of Apostles.
** The Assyrians are members of one of two branches Church of the East, resulting from a schism in the 1970s; the Ancient Church of the East has around 70,000 members and historically used the Julian Calendar, and the Assyrian Church of the East has 400-500,000 members and switched to the Gregorian Calendar during the extremely controversial patriarchate of Catholicos Shimun XXI Eshai, whose actions basically triggered the schism. The two Assyrian churches are working on reunification. The Chaldean Catholics became a Sui Juris Eastern Catholic Church in stages in the 17th and 18th centuries due to a schism along tribal and linguistic lines; Assyrians still speak Syriac Aramaic as their main vernacular language, whereas Chaldeans mostly speak Arabic in thr vernacular, but still worship using Syriac. The Syriac Orthodox and Antiochian Orthodox have some small Syriac speaking minorities who use Aramaic Syriac dialects like Turoyo in the vernacular, but mostly speak Arabic; the Syriac Orthodox, Syriac Catholic, and to a much lesser extent, the Maronite Catholics, use Classical Syriac in worship services.
