The quote from Roosevelt was made in reference to his dismissal of a general for using waterboarding.
The only direct reference to waterboarding for that incident that I have read comes from a Politico article that itself never directly links waterboarding and Roosevelt's decision.
According to that article, "The court-martial cleared the general of the charges, found only that he had behaved with excessive zeal and 'admonished' him against repetition." Assuming the only charge against the general was waterboarding, what you have is a clear difference between what a court-martial board found to be torture, and what one person named Teddy Roosevelt found to be torture. Hardly a consensus. But we can't even go that far, because the article says only:
"Roosevelt responded by disregarding the verdict of the court-martial and ordering the general’s dismissal from the Army. Morris wrote that Roosevelt’s decision “won universal praise” from Democrats, who congratulated him for acknowledging cruelty in the Philippine campaign, and from Republicans, who said that he had “upheld the national honor.”"
It is unclear whether waterboarding was the only act involved, or whether there were other acts as well. The article doesn't address that issue.
The only US military person I am familiar with who was court-martialed and found guilty for acts that included torture was Major Edwin Glenn in 1901. His acts included the burning of villages, and I am not familiar with a legit source that addressed whether he was court-martialed for waterboarding, other acts that were considered torture, the burning of the villages, or all or a combo of things. Again, without specifics on what was decided, you can't tell what drove the final decision.
