In support of the clear-eyed anti-pessimism in the piece, consider the following:
Get to defensible ground; always be making it more so.
Finish medical preps like dental work, cataract removal, and anything that won’t be available during the Disruption.
Clean up your personnel problems; you know who will be a net negative during the war. Arrange transfers for those folks sooner rather than later.
Potable water will keep you and yours alive; make sure your purification plans are both broad and deep.
Make sure that everyone knows the basics of weapons use and safety; you will need ‘all hands’ more often than you’d like.
Never stop prepping.
