For a general fixed duration endpoint cost optimal control problem, the proximal aiming technique of nonsmooth analysis is employed in order to construct a discontinuous feedback law, all of whose Euler solutions are optimal to within a prescribed tolerance, universally for all initial data in a prescribed bounded set. The technique is adapted in order to construct universal near-saddle points for two-player fixed duration differential games of Krasovskii-Subbotin type.
