Lou Pérez, a history professor at UNC Chapel Hill, has probably written more on Cuba than anyone outside of Cuba. He published an op-ed today about ending the embargo.
The disavowal of an untenable policy, however, does not necessarily mean the renunciation of the unrealized purpose, which has always been about toppling the Cuban government, or in Lugar's words – the more common euphemism – about “bringing democracy to the Cuban people.”
Policy approaches often change, to be sure, but assumptions rarely do, and with Cuba they never do.
Obama's “new beginning” possesses a wearisome familiarity: the United States as self-appointed arbiter professing to act on behalf of the well-being of the Cuban people, to bestow upon the Cubans the liberty they are apparently unable to achieve for themselves.
"Wearisome familiarity" is a great phrase.
