Or even an adult who has never gone camping being dropped in the middle of Alaska, the Amazon, or the Ghobi desert. Odds of survival are low and they are gonna suffer from starvation, thirst, getting sick from eating/drinking from the wrong sources, or being prey to something they don’t know how to avoid. Maybe all four!
If they were born and raised in captivity their odds of survival are pretty low. Like someone who always lived in a large city and never went camping being dropped off in Alaska odds of survival.
Rehabilitation only helps so much without the actual experience of growing up with other members of their species in the wild.
Edit: Of course the adults in the wild are the ones that survived until adulthood so I still lean towards attempts to rehabilitate and release, just noting it isn’t as simple as releasing.
Recognizing the countries around Israel doesn’t keep Israel from attacking them whenever they feel like it. Recognizing Palestine is important in the long term, sure, but that won’t matter as long as Israel keeps behaving the same way.
