stripping to her underwear
It varies of course, but most public nudity laws I’ve seen pretty much only specify that genitals and female breasts (and sometimes not even breasts) need to be covered.
There’s a picture in the article, she’s wearing some fairly conservative undies, I’ve seen people wear more revealing clothes just out shopping at Walmart or going for a jog, and she’s certainly showing less skin than you’d see at most beaches or swimming pools.
At worst you might get questioned by the cops about why you’re out walking around in your underwear, but unless you seem like you’re in the middle of a mental health crisis, or refusing to leave a business or otherwise causing a disturbance, it’s kind of a stretch to say you’d be arrested, at least in most halfway modern countries if the cops are enforcing the laws properly (which is of course not a given)
Try 10 years
This whole shit show kicked off with Russia invading Crimea back in 2014 and it’s been going on ever since.
Yes, it escalated in a big way a couple of years ago, but if someone were to, for example, invade Florida, we’d consider that to be the unquestionable start of a war, not 8 years later when they tried to move beyond Florida and attack the rest of the country.
