I do not doubt that many of the efforts taken have made our country safer. However, i have a bit of a problem with the notion that fighting this war on terror has made us in and of itself more safe. As has been noted before there are plenty of things which have been missed, such as a reasonable provision to improve port security, while we have continued to spend money on things that really arent war on terror related (ie iraq). If people have the need to fight radical islam that is one thing, and perhaps it would be safer for the country to take an aggressive stance. The problem with that is, islam is much more of a global religion than we give it credit for, and surely fighting radical islam, does not in and of itself, mean fighting only in the middle east.
Personally its not that i dont think we should be fighting radical islam, as i can see how as a country it probably has to remain a foreign policy issue for quite some time, but i think we have not come close to in any fashion doing it the right way. What i think we have accomplished, is fighting wars on different fronts, very quickly creating a war weary nation, which is not a thing you would have to have when fighting something of an endemic war. If your going to be fighting a war that is by and large unwinnable, it pretty much has been strategized and ran as best as humanly possible. As it has not been, i doubt that it really has made us all that much more safe at the moment.
