Code for 'US must lead militarily to defeat ISIS'

     I suppose if the US had unlimited resources, then anytime an American was attacked or killed by ISIS, the US could simply send forces to wherever and wipe out the offending enemy hostile cell or army grouping.  But this is simply wishful thinking on the part of right-wing conservatives in this country.  Moreover, if the US were to go after every hostile enemy who would harm a US citizen, as a first-line defense of its sovereignty, then at some point even our allies would come to hate us-- certainly to be afraid of us, lest at some juncture we turn on them!  The US would have created a hostile world environment in which to act.  
The Argument for US leadership in the cause to defeat and obliterate ISIS
     Ever since the Arab Spring event swept over the Middle East, Islamic rebels have sought to establish their own caliphate while expanding their own power and might in the countries caught in political chaos, e.g. Libya, Yemen, even Egypt.  As the leading power in the world with the largest military of any country, it behooves the US to recognize its primary and essential mission to eradicate this marauding radical Islamic force not only to protect its own borders but to re-establish what peace and stability there was in the region prior to the advent of the Arab Spring movement. Moreover, ISIS' military aggression has led to the displacement of millions of persons living in the region, giving rise to the emigrant problem for EU countries.
     It is assumed that the US could call upon international cooperation, as through its heavily supported, NATO.
US involvement in serious conflicts and destabilizing situations around the world
     Be it recognized that the US is already confronting and attempting to cope with many threatening situations having implications for the peace and stability of geographical regions in the globe or for the smooth conduct of international trade and commerce:
1.  China's aggressive posturing to overtake its lack of innovation by pirating copyrighted and patent materials from US companies.  Its further aggression in the Asian seas near Japan and the Philippines so as to establish its claimed right to control these waterways.
2.  North Korea's development of ballistic weaponry capable of delivering nuclear bombs and devices even to US shores.
3.  Potential threats from Russia and China to shut down electrical and communications grids in the West.  
4.  The US' own debt that has reached un-heard-of levels heretofore.
5.  The US' efforts to aid the European nations amid worldwide economic slowdown; and to establish a viable EU, retaining the UK within its structure.
6.  Doing whatever is necessary militarily and diplomatically to preserve the independence of formerly Russian-controlled states, as in the Ukraine.
7.  Maintaining some 700+ installations in over 170 countries as a deterrent to the collapse of governments worldwide.
     The list is yet longer.  The point being the ISIS crisis is only one among many that threaten not only world peace but the US' ability to function as a unitary nation.
     Nevertheless, I am convinced that with the advent of Globalization, there's a lingering desire on the part of international financiers to hope with glee that the US might be involved so deeply around the world as to cause its own demise.  These individuals, mindful how the Netherlands dominance gave way to British and French colonization and that to US influence in world affairs, are looking forward to establishing yet another dominant nation or state-cluster in need of goods and services that mean astronomical profits for them.    
The US' Priorities List of degree of involvement
     Obviously, the US must engage in prioritizing how to allocate its resources and restrict its degree of involvement in any particular threatening or destabilizing situation.
     Moreover,  the US recognizes that not only is military might available to handle conflicts but diplomacy.
So the Code for 'US must lead militarily to defeat ISIS' is to my mind that the US should rush towards its own destruction!
