Who does Jefferson blame for the continuation of the slave trade?

Thomas Jefferson attributes the continuation of the slave trade primarily to foreign nations and the economic interests that drive it. He expresses frustration with the British and other European powers for perpetuating the trade, as well as the complicity of certain American interests that benefit from slavery. Jefferson also acknowledges the moral conflict and the difficulties in curbing the trade, reflecting his own ambivalence about slavery and its implications for American society.
