1989, when Nicolae Ceasescu got killed by the Romanian Army officers he ran to for protection.

Pretty much this. Even if your eyes are bad-bad, generally you can find a task you can do, even if it’s “go spread fertilizer on the crop beds over here” or “hold this metal down at this end while I hammer the other end into shape.” People with bad eyesight have historically survived in conditions nearly identical to what a commune of survivors would be facing if the T-virus decided to escape tomorrow or whatever, it’s not magic. Depending on the community you wind up with, you will have SOMETHING that you can do to meaningfully contribute even without eyeglasses.

Don’t forget all the illegal/semilegal weed farmers who are more than happy to put you in the dirt no matter who you are.

A lot of Mormons in the Great Plains take up long range and extreme long range shooting (think sniper shit), mostly because you have enough flat land there to set up proper 1000yd ranges (and enough deserted areas where you can just go plink a target for a couple hours without another living soul around).

Don’t forget Oregon, which was literally founded to be a white ethnostate.

Pretty much this. The number of countries that could wage a full invasion across an ocean, keeping supply lines open, against a near-peer, is pretty tiny - MAYBE the EU if they all pooled resources (and invited the UK along). MAYBE China if they island-hopped (which is its own set of logistical nightmares). That’s really about it.
