Pundits and news agencies have questioned the validity of reports that the Islamic State is beheading children in its conquest of Syria and Iraq. But there is one fact that can't be contested: The Sunni-dominated al-Qaida splinter group is on a war rampage using some of the most heinous and barbaric means to exterminate anyone who opposes it, particularly Christians.

In 2011, President Barack Obama declared, "The long war in Iraq will come to an end by the end of this year." The only thing he didn't count on was that the terrorist enemies of the U.S. decided not to also call it quits on the war.

Last Wednesday, Obama called it quits again with combat operations in Iraq -- or the dropping-bombs-and-not-calling-it-combat-operations operations.

From his vacation spot on Martha's Vineyard, Obama declared: "We broke the (Islamic State) siege of Mount Sinjar. We helped vulnerable people reach safety, and we helped save many innocent lives. Because of these efforts, we do not expect there to be an additional operation to evacuate people off the mountain, and it's unlikely that we're going to need to continue humanitarian airdrops on the mountain. The majority of the military personnel who conducted the assessment will be leaving Iraq in the coming days."

I guess we should be relieved again that we're "pulling out of Iraq," and the Islamic State will retreat from its tyrannical rampages, right? Not a chance.

While Obama was politicizing the success of his in-and-out combat mission, United Nations Secretary-General Ban Ki-moon "called on the international community to do even more to provide protection," according to UN News Centre.

Why? Because just two days before Obama spoke about mission success, the U.N. refugee agency reported that "an estimated 20,000 to 30,000 people remain trapped on the Mountain."

A "profoundly dismayed" Ban added that the Islamic State remains carrying out "barbaric acts," which he said, in UN News Centre's words, "include accounts of summary executions, boys forcibly taken from their homes to fight, (and) girls abducted or trafficked as sex slaves." Even those who manage to get off Mount Sinjar "remain exposed to," Ban said, "a perilous odyssey" to freedom.

How perilous? Here's what we know about the Islamic State's horrific acts over the past few months:

--In July, CNN reported on various Iraqi village residents' descriptions of horrific attacks by Islamic State fighters. The militants "seize local men and pillage homes and places of worships," according to Human Rights Watch directors in Iraq.
