Read this post to see how the author, using excellent documentation (one from the "horse's mouth" (def.): Foreign Affairs, a journal of the directorate of the US ruling capitalist class), reaches this conclusion:
While Washington has lost its war against Syria, it continues its war on peace. It will spoil attempts by Syria to move forward – and by doing so – and more than anything else – illustrating to the world that its own malign interests and agenda wrecked the region – not “ISIS” and not “Iranians” or “Russians.”
The US campaign of spite will continue onward both in Syria and across the rest of the region until an alternative regional and global order can be established that allows nations to sufficiently defend against US aggression and interference and enables the world to move on without those special interests on Wall Street and in Washington driving America’s current battle for hegemony.
