The Islamic State of Iraq and Syria (ISIS) militants boasted on Twitter Saturday that they had executed more than 1,700 Iraqi government soldiers and posted grisly on-the-spot photos. The claim of the Sunni Islamist militants shocked media outlets the world over as this latest Iraq massacre might be the largest since 2003.

ISIS already appalled the whole international community by suddenly taking over Mosul days ago, the second-largest city of Iraq. Their mass murder of thousands of war prisoners this time reveals their atrocity as well as the unpredictable abyss of the Iraq crisis. The US has sent the nuclear-powered aircraft carrier USS George H.W. Bush and two guided missile ships into the Persian Gulf and is hesitating about whether to launch air strikes against ISIS in northern Iraq. It seems the Iraq tragedy is caused by a continuously regenerative power that can never be eliminated by external forces.

Washington waged the Iraq War in 2003 without UN authorization and regardless of objections from major countries including China, Russia, Germany and France. US public opinion has recently been reflecting that the Bush administration might have started a wrong war, although authorized by Congress and a majority of the US public back when the US elite was confident about remolding the Middle East. The democratic system failed to broaden the limited vision of US society on the Middle East.

Thousands of US soldiers were killed at the battlefields of Iraq and tens of thousands of Iraqis lost their lives, for which then president George W. Bush and defense secretary Donald Rumsfeld would not assume any responsibility. This is indeed an error by Uncle Sam. Nevertheless it will be of positive significance to a certain degree if the Western world led by Washington can draw from the brutal war profound lessons that are expected to help change the US' way of "leading the world."

The biggest lesson is that the US is not omnipotent in reforming smaller countries it detests. The West needs to hold in awe the torn and tattered societies of Iraq and Afghanistan, which will release incredible power once their internal structures are disrupted and devour all efforts at peaceful reconstruction. There is no denying that Washington has injected power into globalization by bringing the clout of Western values to every corner of the world. However, many people may have overestimated the political meaning of US cultural communication and mistaken it for a prelude to world domination for the Western political model.

Now the White House is keen on its "pivot to Asia" strategy. History will not simply repeat itself. If the US attempts to scourge East Asia, it will probably adopt different means from those in the Middle East. East Asians should give full play to their wisdom to avoid falling into the trap of Washington.
