The term “global security” can be vague, encompassing any number of issues, from climate change to autonomous weapons systems to food insecurity. For those in positions that require a firm grasp of the subject — be they members of the military, government officials or humanitarian workers — getting a handle on it is no small task, especially when they’re on...
