One Missy Ryan at the Washington Post wants her readers to swallow this nonsense:
While the Obama administration is expanding its effort against the Islamic State, it has resisted calls from some of its Middle Eastern allies to more directly pressure Syrian President Bashar al-Assad, whose long civil conflict has created the conditions that gave birth to the Islamic State and other extremist groups.
The conflict in Syria, started by the U.S. and other international supporters of the Muslim Brotherhood, had nothing to do with the "birth" of the "Islamic State and other extremist groups".
Academic accounts of the genesis of the Islamic State, Jabhad al-Nusra and others point to a much earlier creation of these groups:
A popular narrative holds that the surprising recent events in Iraq can be attributed mainly to the unraveling of Syria.
…
[This] is just part of a picture, one constructed by connecting the dots from events that we can observe, rather than from a careful analysis of the group known as the Islamic State. Consider another possibility: the Islamic State’s resurgence since 2010 in both Iraq and Syria is the result of a carefully crafted plan. The Islamic State counteroffensive in Iraq, conducted under the noses of a waning U.S. presence in the country, created conditions for the Islamic State to establish a new political coalition that remains intact to date. The high-level of military excellence achieved by the Islamic State in their campaign as much as any political factor, has influenced their return and creates a host of challenges for the military, intelligence, and diplomatic professionals tasked with their defeat.
The Islamic State and Jabhat al-Nusra were both part of AlQaida in Iraq (AQI). The were created in reaction to the U.S. invasion of Iraq. After having been temporarily defeated during the "surge" of U.S. troops AQI revived and fought an intense war against the Iraqi government. When the conflict in Syria started the war in iraq was again raging. A part of AQI transferred to Syria under the name of Jabhat al Nusra. It used the eastern part of Syria primarily as a retreat and training space. AQI split in two when the Iraqi part detached itself from AlQaida central in Pakistan as well as from Jabhat al-Nusra and transformed itself into the independent Islamic State.
The conflict in Iraq ignited by the United States is the creation point of these extremists group. The conflict in Syria allowed the growth of these groups into the geographically near eastern parts of Syria but the Syria conflict had no relation to those groups founding. Ahrar al-Shams and the Islamic Front, other extremist group in Syria, were also founded and led by senior AlQaeda members mostly from Iraq. Like the Islamic State and Jabhat al-Nusra these groups do not originate in the Syrian conflict but in a wider and older context.
The origin of these groups lies in the the U.S. war on Iraq. To accuse the Syrian government for their creation is propagandistic nonsense.
