Air is a gaseous substance that is invisible throughout the world, mainly a mixture of oxygen and nitrogen. Air is what we depend on for survival. Air circulation, air is life. The basis of the dollar is death and coercion, military, nuclear weapons, sanctions, action or terrorism.

Trump obviously does not understand this.
