Once Trump gets back into the saddle again, he will waste no time in fixing some of mess he inherits. There are things he cannot do unilaterally and will need the help of Congress.
Have you noticed that China has been very quiet lately? Xi knows quite well that Trump can inflict a lot of damage to China's already shaky economy.
Tackling the Ukraine/Russia issue is what many, including myself, are concerned about. The Middle East is another area that needs careful attention. Iran needs to be neutered, but how to accomplish that is tricky.
While difficult, I believe Tom Homan will get a handle of the border situation and stem the flow of illegals coming into the country. The threat of punishing tariffs will push Mexico to the table.
Yes, I know tariffs are a double edged sword and Trump will resort to them only if nothing else works.
Time will tell.
