War Of Poor Communication?

An educator's style blog made the following observation:

"The War of 1812 could be called the "war of poor communication." Two days before the declaration of war, Great Britain agreed to repeal the naval laws which were chiefly responsible for the conflict. Speedy communication would have also eliminated the greatest battle, the Battle of New Orleans that occurred 15 days after a peace treaty had been signed."
