US President Barack Obama, as senator from Illinois, opposed the invasion of Iraq in 2002 (much before it was actually invaded), and his dim view of this unnecessary war hasn't changed. Instead of criticizing and opposing Obama (as his sliding popularity shows), people should be applauding his consistency of vision and decision-making integrity. Obama didn't get the United States into the mess that is the "war on terror"; on the contrary, he courageously proposed to get Americans out of it. So people who say the US president has no vision or consistency or is decision-adverse are almost psychotically counterfactual.

Obama is now under pressure to re-send US forces into Iraq to help it stop the "triumphant" march of Islamic State of Iraq and the Levant militants from the north to the central part of the country. Obama may not be able to resist this pressure, although he could end up sending a small, compact US unit for the task on condition of pulling it out as soon as feasible. And there is solid reason for Obama to take such a measure.

The Iraq war was a mistake right from the start and committing new mistakes will not right the wrong. The bull-headed George W. Bush administration concocted the mayhem in Iraq against the advice of some of its smartest allies, including Germany and France - not to mention the sincere but quiet reservations of China and opposition of Russia - and persisted with its folly even in the absence of the UN Security Council's approval, which it had desperately sought.
