There has always been a strong element on this site and others of folks asserting that Barack Obama's foreign policy is not incompetent at all. Rather, that he's doing exactly what he intends to do, which is to weaken America's standing on the international scene so as to lessen the need, expectation and ability of the United States to assert its power and authority. Why do liberals want this? Because a) they don't really believe in the virtue of America's influence; b) they don't really have that big a problem with the enemies conservatives would want to confront; and c) they want government to be a force for domestic social engineering, and how dare the Pentagon take up money they want to use for this!
