Though I think Wheaton can make the policy that only a Christian military officer serve as lead ROTC professor, the military is clearly able to simply withdraw the program.
Likewise, I dont think the military adhering to Wheaton's demand is unconstitutional. The ROTC program does serve a secular purpose and the military can make adminsitrative staffing decisions based on a variety of local considerations.
I hope the militiary reaches a compromise and continues to accomodate Wheaton, and any other pre-existing schools with similar requirements. Future schools can be declined. As a side note, ROTC has been at Wheaton for 60 years.
All that aside, should ROTC soldier on at Wheaton, or be re-deployed somewhere else?
