President Obama spoke movingly this week about “never forgetting” the horrors of the Holocaust. He also reiterated his support for Israel and vowed to do everything possible to prevent future genocides.

Welcome words, all.

Question is: Will meaningful action ever follow? Alas, his speech offered little hope.

“We’re going to institutionalize the focus on this issue,” Obama said. “ ‘Alert channels’ will ensure that information about unfolding crises . . . quickly reach decision-makers, including me.”

He noted the first meeting of his Atrocities Prevention Board, aimed at developing “new tools” to expose and address human-rights violations. The board will prepare “the first-ever National Intelligence Estimates” on the risk of atrocities. The State Department will boost “its ability to surge our diplomats and experts in a crisis.”

Great: Form a committee! Issue a report! Send in the striped-pants brigade!

That’ll stop the murderers.

Please. As Nobel laureate Elie Wiesel asked: “Have we learned anything from [the Holocaust]? If so, how is it that [Syria’s Bashar al-]Assad is still in power? How is it that the No. 1 Holocaust denier [Iran’s Mahmoud] Ahmadinejad is still a president — he who threatens to use nuclear weapons to destroy the Jewish state?”

Alas, Obama offered no answers.

Notably, the president did recount the story of Jan Karski, a Polish Catholic who sent the outside world the first eyewitness account of the slaughter of Jews at the Treblinka death camp — evidence, Obama said, that went “all the way to President Roosevelt himself.”

Fact is, though, FDR and his State Department did precious little once alerted.

Yes, they, too, formed a committee and warned the Nazis they would be held accountable. And, indeed, they were — after 6 million Jews had been slaughtered.

The difficult truth for Obama is that real evil sometimes can’t be stopped without bold action — including, sometimes, military action. The troubling truth for everyone else is that there’s little sign Obama is willing to take that action, if need be. (Copyright 2012 NYP Holdings, Inc. 04/25/12)
