President-elect Donald J. Trump’s news conference at Mar-a-Lago was a reminder of what the next four years may have in store.

President-elect Donald J. Trump refused on Tuesday to rule out the use of military or economic coercion to force Panama to give up control of the canal that America built more than a century ago and to push Denmark to sell Greenland to the United States.

N.Y. Times journalist David Sanger says Trump's idea of America first is now less isolationism, more expansionism. He expects changes in the approach to Russia, China and the wars in Gaza and Ukraine.
