S- Macaron appears to be liberal and prefers that America not intervene in foreign affairs. He is very critical of the government, government officials, their motives for certain actions, and the endgame of action.
O- The immediate issue was the arrival of US military forces in Manbij, Syrian. Macaron had to ask why the US decided to place their forces in Manbij, which led him to research the changing decision making process of the American government, which he attribute to the recent change in presidential power.
A- Al Jazeera is a broadcast organization based out of the Middle East (see Overview Page). Macaron's audience is mostly those in the MIddle East affected by the issue of his articles. His audience is also American citizens seeing that he works in Washington D.C. and provides articles to Al Jazeera English. These two categories could include policy makers, reformers, political analysts, even regime leaders.
P- The purpose is obviously to inform his audience of the happenings in Syria, but some may not know that America decided to intervene in the ongoing Syrian war. Some may not have known there was a war in Syria, period. Macaron is educating the American and Middle Eastern public about the US government's decision to back Syria quietly.
S- The subject is this particular article is the decision of the American government to move some of their forces into Manbij, Syria as a show of force.
Tone- Macaron's tone is very critical of the government's decision to move their forces in Manbij, hence the previous assumption that he is liberal. In fact, Macaron's tone is on the verge of incensed. He compared the move to America's invasion of Iraq in 2003 under president Bill Clinton, which after the reading of this article, one can assume he did not approve of.
