Hobsbawm:

"The sudden emergence of an extraordinary, ruthless, antagonistic flaunting of US power is hard to understand, all the more so since it fits neither with long-tested imperial policies developed during the cold war, nor the interests of the US economy. The policies that have recently prevailed in Washington seem to all outsiders so mad that it is difficult to understand what is really intended. But patently a public assertion of global supremacy by military force is what is in the minds of the people who are at present dominating, or at least half-dominating, the policy-making in Washington. Its purpose remains unclear."
