Not only does Trump not have a theory, or a plan, he seems not to remember what he says or does from day to day.  I imagine his ex-wives can testify to his inability to keep promises.  The American people have been hoodwinked into choosing a man who believes he is not accountable to anyone, and whose only principle is 'I got mine, and I'll take yours too if I want it'.  He seems bent on destroying not just this country but the world as well.
