The Kurdish assessment is backed by the fact that IS is able to muster thousands of troops for major assaults simultaneously from Kobani in northern Syria, to Baghdad in Iraq and in several different locales in Kurdistan in between. Based upon the territory under IS control in Iraq and Syria (2,500,000sq.km.) there are between 10 and 12 million Sunni men of fighting age in the pool of manpower IS can draw from. A Western commitment of boots-on-the-ground would have to be closer to the numbers of Desert Storm in 1991 (500,000 to 600,000) in order to "degrade and destroy" the Islamic State as the Obama Administration's plan exists today. Five bombing mission per day ain't gonna cut it.
16 November 2014: According to Islamic State caliph Abu Bakr al-Baghdadi's just released public communique, the list of Islamic State wilayat (provinces) based upon the baya (an Islamic binding oath of allegiance) received from these locales. In addition to Iraq, Syria, Lebanon, Sinai and the Nile valley of Egypt (detailed below) the other acknowledged baya have come from al-Baghdadi's devoted followers in Saudi Arabia; Yemen; Algeria (Army of the Caliph); Libya (Majlis Shura Shabab al-Islam). Interestingly, some received baya have been ignored, particularly those received from non-Arab nations such as Pakistan, Indonesia and the Philippines.
This would indicate a distinct Arab supremacist nature is involved with the initial growth of the Islamic State. The acknowledgement of these baya is found in Islamic State references to these various places as, for example, Wilayat Sinai. Next on the expansionist agenda are Wilayat Jordan and Wilayat Palestine, meaning all of Israel beginning with Judea, Samaria and Jerusalem. The "liberation" of Jerusalem and the rest of "Palestine" is the primary task assigned to Wilayat Sinai, and their brethren in the Nile Valley who will wage war on the Egyptian government currently led by President Abdel-Fattah el-Sissi whom they have identified as "Zionist collaborators." The Islamic State war against Egypt from within Sinai and the Nile Valley is to take precedence over the Liberation of Palestine and Jerusalem. (See Isaiah 19 and Ezekiel 29 for related Bible prophecy).
The Islamic State also has declared another of its objectives is to annihilate the Shi'a sect of Islam in Saudi Arabia, Yemen and, obviously, Iran and Lebanon. They will leave the jihad against the "Crusaders" to their core jihadist partners in Al Qaeda and its veterans in Syria, the newly identified Khorsan group.
15 November 2014: Exactly one month ago today in the first paragraph of Global SITREP D8-14: General Observations I posted information regarding the Sunni terrorist group Ansar Beit al-Maqdis and how they had sworn their jihadist allegiance to the Islamic State in Iraq and Syria, and who are largely funded by the Egyptian Muslim Brotherhood - the same Egyptian Muslim Brotherhood that was so steadfastly supported by the Obama Administration in their uprising against former Egyptian President Hosni Mubarak's government. Remember this because it is both very instructive about a president with two years remaining in the White House and who has long been at war with the government of the State of Israel.
