Yes, we've imposed tactical (and strategic) limitations due to operational risks in our current wars/engagements. The B-2 for example, will never fire a shot in anger since there are so few airframes. It'll be retired in short order after the deployment of the B-21. Same with the F-22. Other than a token deployment to the Mideast with a sortie or two in Syria, they won't see combat unless we get in a hot war with a peer. And until recently, they lacked the required capabilities to attack ground targets. No need to risk them for bomb truck missions. My real worry is that our risk aversion will cause a conventional war to go nuclear in short order, when a more robust conventional military would be able to prevent that. Imagine if we lost a CVN to the Chinese? 5000+ sailors and airmen dead.
