U.S. President Barack Obama, Canadian Prime Minister Stephen Harper and their host, Mexican President Felipe Calderon, emerged Aug. 10 from a speed summit united on recession-fighting and Honduras' ousted leader, but divided on security and trade, the areas that most define their partnership.

The annual three-way meeting lasted barely more than four hours — spanning dinner Aug. 9 and a morning of talks Aug. 10 — and there were no deals to announce.

Obama said immigration changes, a politically explosive subject in the United States and Mexico, would have to wait until next year. He said he expected draft legislation for an immigration overhaul this year, but the matter would not get priority attention until 2010.

The leaders' united front on Honduras produced some of the most animated talk.

Since Honduran President Manuel Zelaya was ousted in a June 28 coup, international demands to return him to power have gone unheeded. The United States has suspended millions of dollars in aid and issued threats of more sanctions but has mostly worked through the Organization of American States to try to resolve the situation. Some, including Zelaya, have criticized that as tepid.

Obama told critics they can't follow decades of complaints about American heavy-handedness in Latin America with today's pleas for more direct intervention. "You can't have it both ways," he said.
