They wouldn't nuke my town. It's not important enough. It is near rich farmland and several food factories, so we'd be well situated to survive and gain an advantage over surrounding communities within the blast zones. (*We means my community. Not sure if I'd be part of the post-nuke privileged class. Getting a foothold in the new world order would be smthg to consider while I'm holed up waiting for the fallout to dissipate.)
First priority would be to load up as much luggage as I can carry with nonperishable food items. That might include a trip to the convenience store, a block away. Lucky for me my recycle is piled up right now. I'd grab several plastic pop bottles and some blankets, soap, toothpaste, first aid kit, barbecue lighter, and maybe a change of clothes if I have room for it.
My daughter's city would be less likely than Toronto to get hit, but might be on the list. So I'd call her and tell her to gtfo of town. At least 20 miles from the parliament buildings, and into a highrise building where nobody will question her presence. She'll need to be at least 10 storeys up to avoid the radiation poisoning. I'd let her know that I'd stay in touch over phone or email if possible. I'd let her know that in a worst case scenario I'd come looking for her when it's safe and tell her not to cross the blast zone looking for me.
Last step: call my sister and ask her to pick up my son from school and meet me at the building with as many supplies as the 2 of them can carry. Being outside of the Toronto blast zone will give us about an extra half hour. I may have to run into my son's school to get him myself. I may not. If there is no time, I may have to trust her and his teachers to get him to me safely.
If he's not in school I would bring him directly to my hideout point, a tall office building a few blocks from where I live.
Not sure if we're close enough to Toronto (the most likely target in a nuke attack) to be in serious danger of radiation sickness. Once the immediate danger is passed, I'd have to devote my hours hiding out to researching the situation, when it will be safe to come out and forage for food, etc.
Idk about the rest of you psychos and your murder parties. I'd be working to keep myself and my family alive.
