Gestures of contempt in return for outstretched hands - today's edition

There's a pattern to this, is there not? The Most Equal Comrade and his nomenklatura play patty-cake with a sworn enemy of America, culminating in an agreement, and the other party immediately steps up the contemptuous rhetoric:

President Raul Castro warned Cubans on Saturday that the United States was determined to end Cuba's socialist revolution despite restoring relations and a visit by U.S. President Barack Obama, saying one-party Communism was essential to defend the system.

"We must be alert, today more than ever," Castro said, speaking in front of a giant portrait of his brother Fidel Castro at the inauguration of the Communist Party's first congress in five years.

Speaking for over two hours, Castro used a defiant tone that belied the breakthrough between the Cold War enemies. He said Obama's desire to end U.S. sanctions was welcome but just a change of "method", in reference to efforts by Washington to bring political change to Cuba ever since the Castro brothers toppled a pro-American government in 1959.

Obama and Castro announced in December 2014 they would end decades of hostility and normalize relations. But on a historic trip to the island last month, Obama angered the government with a speech broadcast directly into Cubans' homes calling for more political freedom and democracy in the one-party state.

Castro and his lieutenants, many of them in their 70s and 80s, faced some discontent ahead of the congress among younger members who are critical of their slow delivery on promised economic reforms in the past five years and a lack of transparency on discussions.

"The key function of the congress is a message that the Obama visit has not changed anything. To reduce expectations," said Bert Hoffman, a Latin American expert at the German Institute of Global and Area Studies.

Once again, what was the point of this "normalization" exercise?
