In 2007 901 US soldiers died in Iraq. That is a 3.4% increase from 2006's 871 deaths (details here). There is also no foreseeable political progress being made (the ostensible reason for the escalation), Iraqis are neither safe nor free, and yet Osama still is.
However, the public is being sold on the idea that this constitutes a "success". It is clearly a marketing success, and one favoring John McCain, the presidential candidate with the most enthusiastic aspirations for escalating and extending our occupation.
