What takes shape, I argue, is a story of betrayal -- American betrayal. By the book's end, many of our heroes don't look so heroic anymore; some of our "villains" end up looking like heroes.

Take Franklin Delano Roosevelt. FDR's reputation as a wartime leader and Depression-fighter earns him a place in the presidential pantheon near the top, not to mention his lavish monument by the Tidal Basin near the Washington Mall.

The historical record -- as extracted from Soviet archives -- proves, however, that FDR's administration was riddled with Soviet agents. Not just one Alger Hiss, who got his hands near the helm of U.S. policy at the State Department. Not just one Harry Dexter White, who managed to do the same via the Treasury Department. The records show there were hundreds of Kremlin-minded operators in government and other institutions who were not only trying to steal secrets but, more important, trying to influence U.S. policy. These operators even include, I argue (based on an extensive dossier of evidence and expert opinion that I invite readers to evaluate for themselves), FDR's top wartime adviser Harry Hopkins.

What "American Betrayal" also argues -- in a narrative anchored to 900-plus endnotes -- is that this makes us due for a massive historical revision.

This is not only a matter of re-examining the past. Coming to terms with what is a strategic "occupation" of the halls of power in Washington by agents of Soviet influence has crucial lessons for what we are undergoing today. There are striking similarities today as vectors of the Muslim Brotherhood and other sharia supremacist groups now seek to influence policymaking in Washington in the post-9/11 era.

These lessons of history apply today to legislators entrusted to defend our constitutional liberties. Remember what happened to Rep. Michele Bachmann and four other House conservatives last summer when they raised questions about Muslim Brotherhood influence in the Washington policymaking chain. Bachmann in particular was crucified, including by the Republican leadership, as the second coming of that devil-figure in American history, Sen. Joseph McCarthy. With rare exception, no one since has dared to raise questions about this still-unaddressed potential national security threat.

To be sure, McCarthy wasn't the only U.S. senator or representative to investigate Communist influence operations and espionage in the federal government in the mid-20th century. Yet having been sold to us as the worst American ever, he has come to symbolize all attempts to bring Kremlin-directed dirty work into the open. McCarthy's radioactive image today effectively stops all thinking about, all investigating and all addressing of malign influence operations and ideological assaults against the country today.

Will Americans one day live in a United States that is a borderless amalgam of Big Brother/Big Government socialism and sharia? Will they look back and scoff at Bachmann's mini-"Muslim Brotherhood Scare"? That's certainly the conventional attitude now, despite the evidence. Meanwhile, we still look back on and scoff at a supposedly imaginary "Red Scare" of 60 years ago, despite massive evidence that the threat was real -- and, as I argue in "American Betrayal," quite successful.

It's time to connect the dots.

All I ask is that readers judge my book for themselves.
