His time in the Senate allowed Blaine to develop his foreign policy ideas. He advocated expansion of the American navy and merchant marine, which had been in decline since the Civil War. Blaine also bitterly opposed the results of the arbitration with Great Britain over American fishermen's right to fish in Canadian waters, which resulted in a $5.5 million award to Britain. Blaine's Anglophobia combined with his support of high tariffs. He had initially opposed a reciprocity treaty with Canada that would have reduced tariffs between the two nations, but by the end of his time in the Senate, he had changed his mind, believing that Americans had more to gain by increasing exports than they would lose by the risk of cheap imports.
