Pseudoreligion in Iraq

Hi Humans,
I see on the television that a group of Humans who call themselves ISIS (whatever this acronym stands for) and are members of the Sunni branch of Islam posted movies on the internet showing them shooting and killing their prisoners who are adherents of the Shiite branch of Islam. It is said that they posted their cruel misdeeds to encourage the Shiites to retaliate which will further divide Iraq between Sunnis and Shiites, thus promoting their cause of creating a Sunni state in Iraq and Syria. This is all being done in the name of religion (supposedly for God). But is this really religion? Does God favor one side over the other? It depends which side you happen to be on. I suppose the best approach to objectivity in the matter is to ask why Human people believe in God in the first place. It seems that as humans developed language and the ability to look at the past and wonder about the future, it became obvious that each creature (Humans included) has a limited life span. This leads to the question of what happens after life, or is there any meaning to existence, any order, any purpose? So humans developed ideas of deities, entities with human qualities and endless life who rule over all us mortal creatures. They also came up with ideas of an after-life where humans go after death. Of course they weren't always clear about what happens to little dogs like me and other creatures. They found it enough to account for themselves. As time went on they refined belief to be of one God which seemed to make more sense than multiple ones. Also they developed science which gave progressively developing partial answers to what is going on but to this day has no clue as to why. So modern religion remains the best we have for why (or in other words the purpose of life), and science is the best shot at what (the details of what is going on). Science and religion each has its purpose and are very compatible as long as each sticks to what it can do best. Unfortunately there are Humans in either discipline who use that discipline for ulterior motives. The ISIS criminals (and they are criminals) did not do their crime for God. They did it to gain power over others. They did it to provoke the Shiites to desire retaliation against Sunni tribal leaders who they believe will now have to depend on ISIS for protection. I would call this perversion of religion pseudoreligion. Historically it is not unique in Islam. Others have used it in the past. But nowadays it seems to be most perfected by certain Moslem groups.
The question for America is what to do now. There is no good answer. The previous Republican administration foolishly pulled America into the mess. Bush broke Iraq and the American people have spent a decade trying to fix the damage. President Obama has won back some of America's power and stature in the world in spite of obstruction by the Republican Congress. But as for Iraq, it has been like putting Humpty Dumpty back together.  So at this point, how much is it necessary for the U.S. to participate in continuing to reassemble the Humpty Dumpty of Iraq? What is now in America's interest?

Who can America depend on? Of the 3 major groups in Iraq, the most reliable, stable, and friendly to the U.S. have been the Kurds. Their military successfully beat back ISIS. They have been consistently friendly to America and America’s allies (including Israel). They have also come to terms with Turkey and produce oil which they ship out through Turkey. Of the other 2, ISIS is definitely America's enemy because of their behavior and alliance with Al Qaeda, the guys who attacked the Twin Towers and the Pentagon. As for the Shiite government in Iraq, they have done a lousy job of creating a united Iraq in spite of all that America has done to prop them up. Let Iran spend their money and lives to support their fellow Shiites in Iraq. From the point of view of America's interests, the only reason to help in supporting the present Iraqi government would be to deny an ISIS sanctuary for the Nine Eleven enemy. On the other hand, an ISIS nation of bad guys in Western Iraq would provide an address that could be bombed when they do bad things, as opposed to a shadowy unfindable terrorist group.
