The battle of the budget has been fully joined by the ideologues of the Democrats and Republicans this week. On the right, we have Monday’s op-ed in the Wall Street Journal by Arthur Brooks, Edwin Feulner and the redoubtable William Kristol in which they argue that the defense budget must not pay for the deficit. Now, on the left, we bring you the views of William Hartung of the New America Foundation. He has aimed high, for almost $1 trillion in cuts. We’ll see if this debate spreads beyond the Beltway and into the conversations of decent people over the dinner table and in bars.
