Is there anyone in the world more unpredictable than newly elected President Donald Trump?

Is there anyone in the world more unpredictable than newly elected US President Donald Trump. One never knows what he'll do. He says he'll end the Ukraine conflict in 24hrs yet he hasn't disclosed any details on how he'll achieve this feat. It's no more than speculation. He stirs the pot to keep it boiling w/ assertions that keeps him in the news. It's anyone's guess what he'll do after he's inaugurated.
