If you are going to design a 'stealth' fighter from paper, then yes, the tactical advantages will be obvious enough that it will create strategic advantages in your favor.
Being 'stealthy' does not mean you ignore the EM threat, it means you still have the burden of mapping out your ingress/egress routes to avoid said EM threats, but if you have to expose yourself to the defender's radar, being 'stealthy' will dramatically reduce your odds of being ID-ed as an attacker.
So regardless of how near is a potential adversary borderwise, you still have to cross hundreds of km of EM hostile environment in order to engage one or many vital targets.
