Not necessarily. Franklin was the American ambassador to France between 1776 and 1785. Also this from Wikipedia (which I accept isn't always to be trusted):
At the beginning of the American War of Independence, Howe was known to be sympathetic to the colonists. He had known Benjamin Franklin, who was a friend of his sister, a popular lady in London society. Howe had written to Franklin in a peacemaking effort. Because of his known sentiments, he was selected to command in America. He was joined in a commission with his brother, General Sir William Howe, head of the land forces, to attempt a reconciliation. A committee appointed by the Second Continental Congress conferred with Howe in September 1776, but nothing came of it.
Benjamin Franklin played a series of chess games with Caroline Howe, the sister of Admiral Howe, at her London home in December, 1774.
The games were a subterfuge for a series of secret meetings with Admiral Howe, attempting to reconcile the American Colonies and Great Britain.
Franklin was appointed the United States Ambassador to France, on 14 September, 1778.
