"No nation in the world has had greater fortune than mine in sharing a continent with the people and the nation of Canada."
"We will always stand with you in the defense of freedom."
"I believe that future generations will have cause for gratitude that two great democracies--Canada and the United States--shared the most generous continent which God has ever granted to man."
"This Texan hopes that you still feel that freedom, for we welcome the comments and the counsel which spring, as yours do, from friendship and understanding."
