Themilitary must be prepared, the document warned, for a “violent,strategic dislocation inside the United States,” which could beprovoked by “unforeseen economic collapse,”“purposeful domestic resistance,” “pervasive public health emergencies”or “loss of functioning political and legal order.” The “widespreadcivil violence,” the document said, “would force the defenseestablishment to reorient priorities in extremis to defend basicdomestic order and human security.” “An American government and defenseestablishment lulled into complacency by a long-secure domestic orderwould be forced to rapidly divest some or most external securitycommitments in order to address rapidly expanding human insecurity athome,” it went on. “Under the most extreme circumstances, this mightinclude use of military force against hostile groups inside the UnitedStates. Further, DoD [the Department of Defense] would be, bynecessity, an essential enabling hub for the continuity of politicalauthority in a multi-state or nationwide civil conflict ordisturbance,” the document read.

"The global economic crisis ... already looms as the most serious one in decades, if not in centuries ... Economic crises increase the risk of regime-threatening instability if they are prolonged for a one- or two-year period," said Blair. "And instabilitycan loosen the fragile hold that many developing countries have on lawand order, which can spill out in dangerous ways into the internationalcommunity."***

"Statistical modeling shows that economic crises increase the risk of regime-threatening instability if they persist over a one-to-two-year period."***

“Thecrisis has been ongoing for over a year, and economists are dividedover whether and when we could hit bottom. Some even fear that therecession could further deepen and reach the level of the GreatDepression. Of course, all of us recall the dramatic politicalconsequences wrought by the economic turmoil of the 1920s and 1930s inEurope, the instability, and high levels of violent extremism.”

Blairmade it clear that - while unrest was currently only happening inEurope - he was worried this could happen within the United States.
