[T]he US has managed to secure its mainland post 9/11 is not only because of an efficient Homeland Security organisation but because the US Special Forces (USSF) are operating in 200 countries including India. Significantly, USSF have undeclared tasks such as conducting proactive, sustained ‘man-hunts’ and disrupt operations globally; building partner capacity in relevant ground, air and maritime capabilities in scores of countries on a steady-state basis; helping generate persistent ground, air and maritime surveillance and strike coverage over ‘under-governed’ areas and littoral zones and employing unconventional warfare against state-sponsored terrorism and trans-national terrorist groups globally. Before 26/11, Al-Qaeda had planned similar operations against New York but could not because the USSF had infiltrated Al-Qaeda. One cannot guard the house by simply barricading it. You must patrol the streets and the area outside.
It is good to hear that all this is going on. It is precisely what the military should be doing. How much does it all cost, compared to the price tag of an F-35 fighter or a Littoral Combat Ship?
