I think any President needs to have the oversight of the House and Senate before the President can launch a first strike using Atomic or Hydrogen weapons of any size. Trump in particular should be monitored by competent non partisan Senior Military advisers before launching a first strike against any country. This includes conventional weapons, Boots on the ground and especially Atomic, Hydrogen or Neutron weapons. Trump's statements in the past have shown how naïve he is with weapons of mass destruction. Most of all Trump has demonstrated that he has no problem what so ever turning away refugees caught in war zones. Women, children & non-combatant men.i believe it would not bother Trump's Conscience one bit to vaporize, burn blind, irradiate & starve millions of people just to claim "I won"
