An interesting article from WSJ. There was indeed a coup attempt in Honduras... by Zelaya. But I can understand why Obama sided with Zelaya. Apparently there is a branch office of ACORN somewhere in Honduras:
A week later some 100 agitators, wielding machetes, descended on the attorney general's office. "We have come to defend this country's second founding," the group's leader reportedly said. "If we are denied it, we will resort to national insurrection."
Sort of the same tactics that helped get Obama elected and continue to demand acceptance of his policies.
