Canadian Bacon (1995)

In a desperate bid to revive his abysmal peacetime approval rating, the president of the United States gets talked into raising his popularity by trying to start a cold war against Canada. But when bumbling U.S. sheriff Boomer and his hair-trigger deputy Honey decide to take matters into their own hands and lead a preemptive strike, they soon find themselves embroiled in a hilarious international incident that's too close for comfort, eh!
