This, a message from the President of one of the most unjust and definitely the most nonpeaceful countries in the world, to the President of arguably the most "just" (in terms of providing food, housing, and health care -- the basic human needs -- to all its citizens), and certainly one of the most peaceful (not having invaded any countries, and whose major foreign excursion of its troops was to help defend Angola against attacking South African forces, a campaign which arguably played a key role in ending apartheid in South Africa).

As for the "sustaining liberty" part, I'm sure the hundreds of legally innocent people being imprisoned and tortured by the United States within the boundaries of Cuba would take issue with that alleged "committment" on the part of the United States.
