There is nothing wrong in dreaming high and trying to achieve those sometimes non-achievable dreams.  That is exactly what ISIS leader is determined to achieve.  Of course, time will tell what happens if they come close to that objective.  However, what is important for the civilized society here is not to ignore the ideology of these militants which is giving birth to these fanatic ideas of creating a caliphate regime in the world. Their slogan of being able to unfurl their flag either on the White House or somewhere else may be immaterial, baseless and non-achievable, but needless to say, their ideology is based on a firm belief that they can achieve this objective.  So, this ideology needs to be changed and, if possible crushed.  The enthusiasm which has become the driving force of their speedy movement in the Middle-East ought not to be the concern of Washington only, but of all countries where these brain washed caliphates are operating and that includes India also. Needless to say, India has been suffering in the hands of these militants for decades and the neighboring country is of no help to eradicate this menace, rather it abets, finances, trains and monitors their operations against India.  Therefore, the slogan emanating from the leader of ISIS could become a headache for the world if not checked and eliminated.  NOW IS THE TIME TO BE AGGRESSIVE AGAINST THIS EVIL.
