The United States faces a world in which the Westphalia order is no longer observed; the state is vulnerable, suffering from a legitimacy crisis, which can only be overcome by a policy that distances it from centres of disorder and moves it closer to centres of order. The actors of this new scenario are not only states, but also ideological movements. As Islam can be a source of disorder, it is advisable to isolate oneself from it (and let it fold back on itself). The advisable grand strategy should be a military strategic defensive coupled with a powerful strategic and tactical counter-offensive; the offensive strategy, undertaken by the current Administration, is a mistake. Instead of a closed political system and a model of multiculturalism within the USA, there should be a pursuit of an open political system and Americanization should be encouraged in order to prevent domestic chaos.
