Learn French;
Ben Franklin was the Ambassador to France.
Benjamin Franklin’s (a signer of our Constitution) letter to Charles W.F. Dumas, December 1775
“I am much obliged by the kind present you have made us of your edition of Vattel. It came to us in good season, when the circumstances of a rising state make it necessary frequently to consult the Law of Nations. Accordingly, that copy which I kept (after depositing one in our own public library here, and send the other to the College of Massachusetts Bay, as you directed) has been continually in the hands of the members of our congress, now sitting, who are much pleased with your notes and preface, and have entertained a high and just esteem for their author”?
Why would I need to learn French to read the United States Constitution?
