The result was, first, compromise, later, under Huskisson's administration at the British Board of Trade, complete abandonment by Britain of the exclusive trade basis of her whole colonial system.
The "retaliatory system" which J.Q.Adams regarded as "a new declaration of independence," was, in fact, quickly taken up by other non-colonial nations, and these, with America, compelled Great Britain to take stock of her interests.

Huskisson, rightly foreseeing British prosperity as dependent upon her manufactures and upon the carrying trade, stated in Parliament that American "retaliation" had forced the issue.

Freedom of trade in British ports was offered in 1826 to all non-colonial nations that would open their ports within one year on terms of equality to British ships.

J.Q.Adams, now President of the United States, delayed acceptance of this offer, preferring a treaty negotiation, and was rebuffed by Canning, so that actual resumption of West Indian trade did not take place until 1830, after the close of Adams' administration.
That trade never recovered its former prosperity.
Meanwhile the long period of controversy, from 1806 to 1830, had resulted in a complete change in the American situation.

It is not a sufficient explanation of the American belief in, and practice of, the theory of protection to attribute this alone to British checks placed upon free commercial rivalry.
