What will it take? A few of our comsats "disappearing?"
Comsats are the least of our worries. If DoD space based assets were at risk from the Chicoms because they held the high ground, then that would be news of the first order. I hate to root for China but in this case I will make an exception.
As for the He3 situation. Former astronaut, former Senator, Harrison Schmidt has been on a long campaign to go after He3. I don't think he has made an adequate business case to support his position. It is conceivable that we could build enough earth-lunar infrastructure over years to make it an ecomically viable proposition.
