At least for the next 2500 presidential cycles or so the chances of the Yellowstone Supervolcano erupting is considered quite low. We have some understanding of the physics involved, there's not enough lava and magma in the chambers currently for such an eruption. Even if a previously unseen phenomenon started to rapidly fill those, rapidly on a geological scale is still measured in thousands of years.
Also, similar things like "the Big One is due in the Northwest" are just sensational headlines. The Cascadia Subduction Zone indeed produces earthquakes every 3-500 years and the last one was in 1700 but that doesn't mean there's an equivalent of a hourglass. It just means there's a historical average of that.
And it's the concern of FEMA to act after something like this happens, not a matter of national security. National security concern, I imagine, would involve defusing these via some military ways and defusing such events are far beyond the capability of humankind at this time.
