This report on the Today programme from the Democratic convention in Boston includes an interview with Madeleine Albright (scroll down to 0842). The former Secretary of State uses the word "realism" and its cognates several times, and argues that the foreign policy of a Kerry administration would be based on a sober assessment of America's "national interest". She also argues for "internationalising" the reconstruction in Iraq, as does Richard Holbrooke, who's interviewed very briefly on the merits of, inevitably, "multilateralism". Now, of course, making more strenuous efforts to sell American foreign policy abroad is one thing (and a desirable thing at that); shrinking from the responsibilities of a Wilsonian commitment to spreading democracy in the Middle East is quite another. It's not yet clear to me that the line recommended by Patrick Belton of OxBlog (which I discussed here) is the one the Democrats are taking; that is, it isn't clear that they're saying they'll do the same (democracy promotion), only better (with multilateral support).
In fact, David Adesnik's update on foreign policy discussions in Boston isn't promising: "It's extremely disappointing to see Democrats talk only about alliances and multilateralism while completely ignoring the imperatives of democracy and human rights. The Democrats used to be the party of the idealists, but now their claim is tenuous at best."
ADDENDUM: However, Joshua Marshall makes a compelling case for an idealist reading of Kerry's vision for international affairs. His conclusion is that the "marriage of power and values is the essence of the foreign-policy vision espoused by leading Democratic thinkers. Out of political caution Kerry's campaign advisers still tend to seek the safety of a Scowcroftian middle ground, but the foreign-policy advisers who would serve President Kerry have quite a different vision—much more ambitious and expansive than anything pursued by the first Bush Administration." Go, as they say, and read the whole thing.
