In between either and or

In logic, it's called bifurcation, the false-either/or dilemma. Here is the problem:

For nearly five decades, the United States has pursued a policy toward Cuba that could be described as incredibly stupid.

It could also be called childish, irresponsible and counterproductive -- and, since the demise of the Soviet Union, even insane. Absent the threat of communist expansionism, the refusal by successive American presidents to engage with Cuba has not even a fig leaf's worth of rationale to cover its naked illogic. Other than providing Fidel Castro with a convenient antagonist to help him whip up nationalist fervor on the island -- and thus prolong his rule -- the U.S. trade embargo and other sanctions have accomplished precisely nothing.

Now, with Fidel ailing and his brother Raul acting large and in charge, the United States has its best opportunity in years to influence the course of events on the island. George W. Bush, as one might have expected, won't do the right thing. It will be up to the next president.

And here is the bifurcation: John McCain -- continue the hard-line approach of the last 50 years; Barack Obama -- conduct direct diplomacy with Cuba's leaders. Neither on of those is really a good option. With McCain's way, we will keep getting the same unintended consequences. Obama's way will give tyrants everywhere the wrong idea.

The better way: Just end the embargo. Let Americans trade with Cuba, travel to Cuba, send money to Cuban relatives. Nature will take its course.
