Entering US with nuclear bomb is no problem

I don't think coordinating with allies is going to solve the problem as much as some would think. From what I hear, there hasn't been a breakdown in border cooperation with the Canadian government, and the border problem with Mexico is being addressed in Congress. Even then, the fact that a team of white, highly trained security agents managed to bring radioactive materials into the country isn't that big of deal, but if the radioactive sensors aren't working, then we have a problem with our technology and should correct that, rather than jump to the conclusion that we're all on the cusp of certain death.

Jam it back in, in the dark.
