Every Nation for Itself

President Trump wants to return to the 19th century's international order. He will leave America less prosperous—and the whole world less secure.

- By Robert Kagan

The Trump administration’s National Security Strategy made it official: The American-dominated liberal world order is over. This is not because the United States proved materially incapable of sustaining it. Rather, the American order is over because the United States has decided that it no longer wishes to play its historically unprecedented role of providing global security. The American might that upheld the world order of the past 80 years will now be used instead to destroy it.

Americans are entering the most dangerous world they have known since World War II, one that will make the Cold War look like child’s play and the post–Cold War world like paradise. In fact, this new world will look a lot like the world prior to 1945, with multiple great powers and metastasizing competition and conflict. The U.S. will have no reliable friends or allies and will have to depend entirely on its own strength to survive and prosper. This will require more military spending, not less, because the open access to overseas resources, markets, and strategic bases that Americans have enjoyed will no longer come as a benefit of the country’s alliances. Instead, they will have to be contested and defended against other great powers.
