"The World After Trump: How the System Can Endure," by Jake Sullivan — Hillary Clinton's chief foreign policy adviser, now at the Carnegie Endowment writes in the March/April issue of Foreign Affairs. Sullivan previously served in the Obama administration as State Department director of policy planning, and national security adviser to Vice President Biden.

The key quote: "Trump ... has thus far been unable to do the level of systemic damage in foreign affairs that he threatened on the campaign trail. He has ... been constrained by Congress, by his own national security team, and by reality."

More from Sullivan...

• "[H]is reelection would confirm that Trumpism is in fact the new normal in the United States, not an aberration, causing other countries to take more decisive steps to rearrange their relationships and commitments."
• "On the other hand, the election of a new president in 2020 would say something quite different — and allow the United States to resume its leadership role."
• Key sentence: "In every dimension — from technology to security, development to diplomacy, economic dynamism to human capital — the United States’ advantages are still significant."
• "The opportunity remains to reconstitute the old consensus on new terms."
