It would be hard to overstate the significance of Barack Obama's blunder. As a certain junior senator from New York said during the primary season, while John McCain has obviously passed the Commander-in-Chief threshold, it's not clear Obama has. If there is one fundamental challenge facing the Dem candidate in this campaign, it is to prove that he has the values and the toughness necessary to protect our country against the terrorists who seek to destroy us.

Yet now—in an interview with ABC's Jake Tapper—Obama has proposed a read-them-their-Miranda-rights approach to dealing with the likes of Khalid Sheikh Mohammed.  It's the policy equivalent of Dukakis-in-a-tank, and is likely, in this NewsBuster's opinion, to have an even more harmful impact on his campaign. The McCain camp has wasted no time in weighing in.  In a conference call yesterday, former CIA director James Woolsey said Obama's advocacy of giving terrorists access to U.S. courts was an "extremely dangerous and an extremely naive approach to terrorism." 

Discussion on Morning Joe today among, on the one hand, Barack fans Mika Brzezinski and WaPo's Jonathan Capehart, and on the other a Joe Scarborough preaching realpolitik, revealed just how vulnerable Obama is on the issue. I'd encourage readers to view the extended video clip here, but for present purposes will focus on one exchange:

When Mika Brzezinski gushed over Pat Buchanan's knowledge of WWII history today, was she aware that her hero has criticized Britain for coming to the defense of her father's native Poland when Nazi Germany invaded it?

Buchanan has been a member of the Morning Joe panel this week. Much of today's talk has focused, with a Bush-bashing panel of guests, on President Bush's condemnation of appeasement in remarks to the Israeli Knesset. At 8:12 AM ET, the show rolled video from last night's Hardball of Chris Matthews's hectoring of radio talk show host Kevin James over the latter's inability to state precisely what it was that Neville Chamberlain did in attempting to appease Adolf Hitler. As I noted here, Chris managed to stumble on some history of his own during that segment, but MJ didn't deign to discuss that embarrassing fact.

Willie Geist turned to Buchanan to answer the question that James couldn't.
