After a week abroad that gave him at least physical distance from the chaos in his West Wing, President Trump this week will confront decisions on three questions that will affect the rest of his term:

Whether to embrace the Paris climate accord, dial back U.S. commitments, or renounce it.

How to structure a crisis-communication apparatus to contain the Russia response, so it doesn’t preoccupy the entire West Wing, and how it’ll interact with legal and P.R. operations on the outside.

What additions to make to his senior staff, and whether anyone should go.
