Strengthening the liberal world order (Brookings)

The world order that was created in the aftermath of World War II has produced immense benefits for peoples across the planet. The past 70 years have seen an unprecedented growth in prosperity, lifting billions out of poverty. Democratic government, once rare, has spread to over 100 nations around the world, on every continent, for people of all races and religions. And, although the period has been marked by war and suffering as well, peace among the great powers has been preserved. There has been no recurrence of the two devastating world wars of the first half of the 20th century.
