Within days of Richard Nixon's inauguration in January 1969, national-security adviser Kissinger asked the Pentagon to lay out his bombing options in Indochina. The previous president, Lyndon Baines Johnson, had suspended his own bombing campaign against North Vietnam in hopes of negotiating a broader cease-fire.

A new book by 'New York Times' reporter Charlie Savage, 'Power Wars,' suggests that there has been little substantive difference between George W. Bush's administration and Obama's when it comes to national-security policies or the legal justifications used to pursue regime change in the Greater Middle East.

Decades before President Richard Nixon bet his re-election on winning the Dixiecrat vote, Wilson worked out his own Southern Strategy. Even as he was moving the nation to war, Wilson re-segregated Washington and purged African-Americans from federal jobs.

Wilson won re-election in 1916, his campaign running on the slogan, 'He kept us out of war.' But he could then betray his anti-war supporters knowing that a rising political coalition - made up, in part, of men looking to redeem a lost war by finding new wars to fight - had his back.

Defenders of Wilson are correct to beg for context when considering his legacy. But it is they who ignore the context: the role Wilson played in using war, including Haiti's racist counterinsurgency, to nationalize white supremacy, militarism, and Christian evangelism.

In the 1960s, after the Cuban Revolution, CIA and FBI agents often coordinated their activities with anti-Castro Cuban exiles.

In 2000, just before leaving the White House, Clinton ratcheted up military aid to Colombia. Plan Colombia, as the assistance program was called, provided billions of dollars to what was, and remains, the most repressive government in the hemisphere.

The CIA's always-useful World Fact book says that a staggering 6.3 million Colombians have been internally displaced (IDP) since 1985, with 'about 300,000 new IDPs each year since 2000,' the year Bill Clinton enacted Plan Colombia. Added up, that's 2.4 million people during Clinton's eight-year presidency.

Hillary Clinton became secretary of state under Barack Obama. It's hard to convey just how stunningly cynical she has been on Colombia: In 2008, running against Obama, she opposed, in unambiguous terms, a free-trade deal with Colombia.

The removal of the British after the American Revolution opened the floodgates of paramilitary ranger power. For instance, in 1786, ranger units, including one that included Daniel Boone, attacked a number of friendly Shawnee towns along the Mad River.
