Imperialism is the factor in American policy, not just since 1898, but in fact long before it when we were expanding across this continent and taking away Indian lands in order to enlarge the territory of the United States. We have been an imperial power and an expansionist power for a very long time.
We should have an army so organized and so officered as to be capable in time of emergency, in cooperation with the National Militia, and under the provision of a proper national volunteer law, rapidly to expand into a force sufficient to resist all probable invasion from abroad and to furnish a respectable expeditionary force if necessary in the maintenance of our traditional American policy which bears the name of President Monroe.
I met many Russians over the years who were convinced my brothers and I were a cabal, pulling strings behind the scenes to shape American policy. The Soviets had no conception of how a pluralistic democracy works and believed elected officials, up to and including the president of the United States, were only figureheads acting out the roles dictated to them by the real "powers that be" - in this case, my family.
The main implication is a remapping of the world in line with American policy and American interests. Natural resources are limited, and the United States wants to make sure that its own population is kept supplied. The principle effect of this will be for the United States to control large parts of the oil which the world possesses.
For the last eight years, American policy toward Iraq has been based on the direct threat Saddam poses to international security. That threat is clear. Saddam's history of aggression leaves little doubt that he would resume his drive for regional domination and his quest for weapons of mass destruction if he had the chance.
It is a key fact about American policy in Vietnam that the withdrawel of American troops was built into it from the start. None of the presidents who waged war in Vietnam contemplated an open-ended campaign; all promised the public that American troops would be able to leave in the not-too-remote future. The promise of withdrawel precluded a policy of occupation of the traditional colonial sort, in which a great power simply imposes its will on a small one indefinitely.
I've always criticised American policy when I've disagreed with it. Just as I've criticised British policy. I was violently anti-Suez and pro-American in 1956, just as I was violently anti-Soviet on the invasion of Hungary which took place at the same time.
