In my opinion, targets "mean Something" when they have a direct impact on the situation at hand, ie. Fighter Hangars at a base under siege, or an enemy CV that is launching attacks on a friendly base.
Also meaningful, but not as direct would be a vehicle base that spawns into an airfield town which we are attacking.
Although I realize Startegic targets do play into the overall war effort, they do not have enough effect to warrent their destruction.
Simply put, a country could reset another without ever touching it's strat targets. Now, it would be somewhat easier, of course, but frankly, I doubt most of the community knows the value of strat targets and their operational effect on the overall war.
Strat, in my opinion, should have much more direct effect on the operation of A/C and GV's, therefore making strat targets contested areas, which will draw bomber raids, and interceptions.
To summarize, I do no think Strat targets are meaningful because they are easily repaired, have little effect on the overall war effort, and are much to easy to devestate by greenest of bomber pilots.
