Nuclear proliferation and global warming are two big issues that Donald Trump is wrong about. They're also the two biggest threats to our planet. Nuclear war followed by nuclear winter could end most life on earth within a matter of weeks or months. Global warming/climate change, though not as immediate a threat as nuclear war and its fallout, is inexorably leading to a more dangerous and less hospitable planet for our children and their children.
What does "The Donald" believe? On nuclear proliferation, which only makes nuclear war more likely, Trump is essentially agnostic and even in favor of other nations joining the nuclear club, nations like Japan, South Korea, even Saudi Arabia. When all countries should be earnestly working to reduce and then eliminate nuclear stockpiles, Trump is advocating their expansion. (An aside: recall in a previous debate that Trump had no idea what America's nuclear triad is; add intellectual sloth to his many sins.)
On global warming, Trump is essentially a skeptic on whether it exists ("hoax" and "con job" are expressions of choice), even as he seeks to protect his resorts from its effects. Along with this rank hypocrisy, Trump is advocating an energy plan that is vintage 1980, calling for more burning of fossil fuels, more drilling and digging, more pipelines, as if fossil fuel consumption was totally benign to the environment and to human health.
