Trump has promoted a number of plans to make America strong – at other countries’ expense. Given his “we win; you lose” motto, some of his plans would produce the opposite effect of what he imagines.

That would not be much of a change in U.S. policy. But I suggest that Hudson’s Law may be peaking under Trump: Every U.S. action attacking other countries tends to backfire and end up costing American policy at least twice as much.
