Foreign entanglements

From an Australian perspective, one of the key questions we should ask of the US presidential candidates is, which one is more likely to see Australia getting involved in another US-led military action? Those who advocate a McCain presidency as best for Australia's interests need to keep things like this in mind:

Most American politicians, of course, would immediately dismiss the idea of sending the military into Zimbabwe or Myanmar as tangential to American interests and therefore impossible to justify. McCain didn’t make this argument. He seemed to start from a default position that moral reasons alone could justify the use of American force, and from there he considered the reasons it might not be feasible to do so. In other words, to paraphrase Robert Kennedy, while most politicians looked at injustice in a foreign land and asked, “Why intervene?” McCain seemed to look at that same injustice and ask himself, “Why not?”
