To the Editor.
—In his Commentary,1 Dr Chelala proposes negotiations between Cuban and US physicians as an avenue toward a more "open and democratic society" to benefit the Cuban people.Chelala's political naïveté assumes that Castro will go along with any type of rapprochement that will endanger his absolute hold on power. To the contrary, this softening of the embargo as proposed by Chelala and others will be used by Castro toward his own goals of survival. At any time Castro will stop any moves designed to threaten his full dictatorship with swift action. The shooting down of 2 unarmed small planes over international waters with the loss of innocent lives attests to that.The only embargo worth lifting is the one Castro's illegitimate government has on the Cuban people.Castro's days are numbered. The only rational policy toward Cuba is to take the steps to accelerate this process.
