9-11-2001, its genesis, circimstances and consequences, is a searing but miniscule representation of the deadly impact of everything amerikan on the rest of the world.
Assessing whether 911 was an inside job is primarily a political, not technical, assessment: what is the geopolitical context, "who benefits"? It means taking into account the entire past as well as present violent history of american capitalism's white supremacist quest for 'manifest destiny'. Those who insist the U.S. govt. could never commit such a heinous crime reflect the inculcated popular ignorance of america's racist history, born and fattened on genocide, slavery and unprecedented crimes against humanity -- including manufactured pretexts for all its imperialists wars for global 'supremacy'. 911, like all other events, can only be understood in this context of past history and the present deep structural crisis of U.S. capitalism driving the bipartisan agenda to secure full-spectrum dominance before other major, now capitalist, powers -- China and/or Russia -- sink the U.S. hegemonic empire.
Neo-liberal imperialist democrat Zbigniew Brzezinski laid out the 'imperatives' for U.S. dominance in his 1997 THE GRAND CHESSBOARD: American Primacy and its Geostrategic Imperatives, tactically advocated more gunboat diplomacy than his 'neocon' imperialist successors who believed all-or-nothing-now militarily, whose global rampage has intensified the U.S. crisis and global resistance to its 'unipolar' thuggery.
Neoliberal or neoconservative, imperialists agree that U.S. capitalism's crisis and strategic weakness demands exceptionally drastic measures. Analyses of the individual 'trees' in the U.S. jungle must be framed in this context because what is at stake is the survival, or death, of U.S. capitalism...and thus the world and all of humanity.
