John Quincy Adams actually said...

"These papers were prepared at the close of the last session of Congress, at too late a period to be then acted upon."

"I shall, indeed, in the first instance, consider the assembly as merely consultative."

"My first and greatest inducement was to meet in the spirit of kindness and friendship an overture made in that spirit by three sister Republics of this hemisphere."

"It was not considered a conclusive reason for declining this invitation that the proposal for assembling such a Congress had not first been made by ourselves."
