Actually, the quotation in question is:
"Our Country! In her intercourse with foreign nations
may she always be in the right; but our country, right or wrong.

Stephen Decatur, toast given at Norfolk,VA, 1816.

I prefer John Quincy Adams' response in a letter to John Adams,
August 1816:

"I can never join with my voice in the toast which I see
in the papers attributed to one of our gallant naval heroes. I
cannot ask of heaven success, even for my country, in a
cause where she should be in the wrong. Fiat justitia,
pereat coelum. My toast would be, may our country be
always successful, but whether successful or otherwise,
always right."
