That would provide the country with a healthy debate and would probably drive the president to get his hands more directly on the problem.

 At a grander level, the whole outreach to Islam by the United States seems to be unformulated and largely unacted upon by the Bush government. This, admittedly, is a formidable challenge. But it is central to our entire war on Islamic terror. Ultimately, Islamic terrorism will be solved -- if it is solved -- by Islam itself, which is in worldwide ferment.

 The terrorist-jihadist faction of that great passion is tiny but overbearing. We need to be reaching out and helping to shape and empower the non-jihadist reformers to win their struggle against the terrorists in their midst. Their struggle will also be against the authoritarian governments that currently rule most of Islam, and with whom we are currently loosely allied.

 If Senator Kerry has developed any thoughts on this matter, he should engage the president in robust debate. If he hasn't developed any thoughts, that tells us something about his seriousness of purpose in running for president.

 Nothing has been more controversial than the carrying out of preventive wars by President Bush. If Mr. Kerry disagrees with that central strategy of the Bush doctrine, he should explain himself in detail. In the past, Mr. Kerry has been on both sides of the issue, but no matter. Let him give a major policy address in which he lays out, with precision and wisdom, when and if he would start preventive wars.

 If he is categorically against them, let him explain how he would otherwise protect the country when there appears to be a building threat. For example, what would he do next year about Iranian and North Korean nuclear weapons?

 It will take some political courage to march into such tricky and controversial matters. On the other hand, the debate would be useful. If Mr. Kerry would start talking about things that matter, nobody would waste their time talking about his war ribbons, SUVs, $5,000 bicycle, expensive haircuts and other amusements which currently seem more important to the top journalists in the country than anything Mr. Kerry has said recently.
