After Vice President Garret Hobart died in 1899, the New York state party leadership convinced McKinley to accept Roosevelt as his running mate in the 1900 election. Roosevelt campaigned vigorously, and the McKinley–Roosevelt ticket won a landslide victory based on a platform of peace, prosperity, and conservation. The Great Rapprochement had begun with British support of the United States during the Spanish–American War, and it continued as Britain withdrew its fleet from the Caribbean in favor of focusing on the rising German naval threat. In 1901, Britain and the United States signed the Hay–Pauncefote Treaty, abrogating the Clayton–Bulwer Treaty, which had prevented the United States from constructing a canal connecting the Pacific and Atlantic Ocean. The long-standing Alaska boundary dispute was settled on terms favorable to the United States, as Great Britain was unwilling to alienate the United States over what it considered to be a secondary issue.
