I didn't mean base your decision on "if a world event happens", rather, take a job offer now (you can always jump ship later) as insurance against a world event.

I'm really am glad everything worked out for you, but I know several folks that were set on AA, and have now had to move on due to the year long delay in getting a class. They can always jump ship to AA if a class date ever gets offered. If a class date doesn't get offered, they'll have a great career at choice B or C. Ironically, I wasn't really interested in AA, but that's where I am, and pretty optimistic about my future here.
