In a summary article, testimony by Defense Secretary Caspar W. Weinberger to the effect that officials in the Reagan administration who thought the Iran initiative was a good thing did not want the president to hear dissenting opinions, such as Weinberger's, was erroneously attributed to former White House chief of staff Donald T. Regan in some editions yesterday. (Published 8/2/87)

Former White House chief of staff Donald T. Regan concluded his testimony yesterday and made these points. ON REAGAN'S REACTION TO SUGGESTIONS OF A PARDON

Early last December, the possibility of a pardon for former national security adviser John M. Poindexter and his aide, Lt. Col. Oliver L. North, was raised with President Reagan and, Regan testified, the president rejected the idea immediately. He said Reagan's reasoning was that "to grant a pardon means you think somebody's committed a crime. You only pardon for a crime." Reagan "didn't know what the crime was" because no evidence had been presented to him. ON WHO WAS THE WEAKER SIDE IN THE IRAN-IRAQ WAR

Sen. Sam Nunn (D-Ga.), referring to Regan's notes of a meeting of high-level administration officials with the president last Nov. 10, had a sharp exchange with Regan over a statement, attributed to Reagan, that Iran was the "weaker" side in the Iran-Iraq war.

"Here you had the president of the United States giving what is essentially erroneous policy, a policy statement. It wasn't a small detail. It was a question of who our government believed was winning that war," Nunn said.

Regan testified that none of the officials at the meeting corrected the president. ON BEING 'FROZEN OUT'

After Regan testified that he was often in the dark about the Iran initiative, Sen. Paul S. Sarbanes (D-Md.) said, "You, in effect, were frozen out there by Adm. Poindexter. . . . What happened in all of this is, in effect, there was a junta within the government of the United States."

Sarbanes referred to a computer message from North to Poindexter that said, "I have no idea what Don Regan does or does not know re my private operation." Poindexter replied, "Don Regan knows very little of your operation, and that is just as well."
