A couple things to consider on this. What if you are maxing damage on the enemy’s IC, and/or they are not fixing it? If they also have bases that they will want to use, it gives you another option to make them spend IPC’s, and use your strat bombers if you’re not using them for anything else.
Like in my current game with Funcioneta, he built a major IC and a naval base on Korea with the USA. I had lots of Strat bombers with nothing much else to do, so bombed them both. He needed the naval base fixed so he could move boats 3 spaces. My bombers were of no use for defense and had nothing else to do, so it was a decent option to be able to bomb the Major and the NB at the same time.
Hey, guys, when I asked Krieg about this same thing, he made a VERY interesting point. Depending on timing, you could bomb an enemy Base and it would then be unusable to their ALLIES until the base owner’s next turn. So you can effectively disable the capability without your enemy being able to fix it. You heard it here first. :-D
