If Trumpy wins he will most likely finish the wall and barrier to the south and claim that as a great American achievement to stop the immigrants and refugees from destroying the American dream and that he is creating a great America again free from the foreign invaders.
He will share with Putin the spoils of Europe to make them both believe they are the champions of the world.
He will fall under the spell of his desire to see North Korea as a friend and try to split power with China in the East Asia region or come to blows with China.
Anything may happen if he wins, he is likely to trumpet every move as being great for America and great for him. He will want the last chance to make his name and mark in the history books. At his age time is running out for world greatness.
