1.) Open any mission you made and check the intel on it.
2.) press clear to start something new
3.) check the intel again - the intel stayed the same.

Its somehow nice to have the ability to transfer the intel to an "empty setting" - maybe include the hint in the mouseover like "Clear (keep Intel) [Ctrl+N]". Or include another button with "clear all".

Please do NOT replace the intel-values with default ones - keep the ability to transfer the intel from one mission to the other!
