Ballistic missiles will be one threat that is considered, he acknowledged, especially as countries like North Korea attempt to acquire and expand their missile and nuclear capabilities — but there will be many others like cyber threats.
Many Canadians were stunned in September when the deputy commander of Norad, Lt.-Gen. Pierre St-Amand, revealed that the current U.S. policy is not to intervene in the event of a ballistic-missile attack on Canada. The revelation came amid growing concern about North Korea's nuclear and ballistic-missile capabilities, which the country has showcased numerous times with a variety of tests in recent months.
U.S. Defense Secretary James Mattis has said the latest test earlier this week showed North Korea is continuing to build missiles that can "threaten everywhere in the world." But Vance said the rogue state still doesn't have the ability to reach Canada with a missile, and that "we're protected against the threats that exist now."

The underlying message in this cartoon is that of we have to power hungry leaders in a conflict with nukes at their disposal.
