Hunkered down in the presidential palace, Enrique Peña Nieto, the unpopular leader of Mexico, was besieged on both sides. The new American president, Donald J. Trump, had just ordered the construction of a border wall between the two countries, and the public outcry in Mexico was deafening. Top cabinet officials, meanwhile, counseled caution, urging Mr. Peña Nieto not to cancel his meeting with Mr. Trump at the White House next week. – New York Times
Editorial: Mr. Trump is a foreign-affairs neophyte, but he is already learning that nations can’t be bullied like GOP candidates or CEOs. They have their own nationalist political dynamics and when attacked they push back. Mr. Trump said as a candidate that he’d treat America’s friends better than Mr. Obama did, but his first move has been to treat Mexico like Mr. Obama treated Israel. On present course he may get comparable results, or worse. – Wall Street Journal (subscription required)
