And so, in a masterful display of the unpredictable shift of geopolitics, the day was 'saved' when the Iranians decided to step in to bail out their proxy in charge of Iraq. Iranian soldiers, unlike the soldiers of the US-created and US-equipped Iraqi army, were more effective in fighting a relatively small number of militants who demonstrate one of the most basic and dangerous aspects of civil wars. Specifically that when they begin in one country, that seldom means that they stay within the border of that country. In a fine demonstration of the success of the anti-Iranian and supposedly anti-Islamist policies of the United States, a force predominantly supplied by one of the most fanatical regimes in the Middle East, a regime inherently dependent on the United States, is fighting a war with a proxy of the Iranians who have an army equipped by the United States.
More such successes, and Iran will be the geopolitical overlord of all of Southwest and Central Asia. What precise benefit did the overthrow of Mr. Hussein get the United States again?
