In a war, economy does not matter. Everyone is hired. Everyone is payed.
Anyways, America does already have the strongest army. wink wink.
North Korea has the largest army with 1.2 million active duty and 8 million reserve. but their one sandwich away from starving.
the United States will NOT plant nukes on North Korea because of the winds, it will affect the whole western hemisphere, so if we do that, their will be nuclear contamination in the united states, Canada and mexico.
