No doubt the leaking of diplomatic private communiqués is not the best thing that could happen to the United States. But it does do something for the Republican presidential hopefuls for 2012: it offers an opportunity for these candidates to make credible campaign foreign policy proposals.
Our Republican candidates for 2012 have an opportunity that George W. Bush did not have: a road map of what has been done by both Bush and Obama and thereby the chance to suggest credible alternatives to not repeat past foreign policy mistakes. And it places Obama or Secretary Clinton, should she change her mind and run, in the "also ran" category because they were both part of the problem.
This leak is a game changer for the Republicans and should not be wasted.
