If I caulk the inside why do I need to caulk the outside? Isn't the air

To keep water out of the walls. The caulk on the inside is for airflow,
and looks.

I forgot to mention that the new windows I am installing are completely
SEALED from any air/water leaks. I guess the caulking would be a BACKUP
measure.
