Jimmy Carter damage involved abandoning the troops and cowardly officers.
Obama/Bidon’s damage is much greater, imo. Not only did they put in cowardly officers, but actively hostile ones. The soldiers had to fully throat support for open sexuality between homosexuals and transgenders or they cold find themselves in getting a dishonourable discharge, confiscation of their pensions and even possibly a stay at Leavenworth.
I don’t know how to undue that within any single term.
