CARACAS, Venezuela — The United States often takes a leading role in calling out the world’s most dangerous places, warning its people about the risks of traveling to countries that are at war, under terrorist threats, experiencing civil unrest or displaying significant anti-American sentiment.

The latest mass shootings have triggered a sharp role reversal, with three countries warning their citizens about the risks of traveling to the U.S.

Venezuela, Uruguay and Japan issued warnings to varying degrees following the deaths of 31 people over the weekend in Dayton, Ohio, and El Paso, Texas. Each warning noted U.S. gun violence, and at least one was laced with a dose of political payback.

Without directly naming President Donald Trump, the government of Venezuelan President Nicolas Maduro blamed the surge in violence on speeches emanating from Washington that are “impregnated with racial discrimination and hatred against immigrants.” It urges Venezuelans to postpone U.S. trips.

Countries such as Australia, New Zealand and the Netherlands have not issued new warnings in recent days, but they have longstanding advisories for travelers of mass shootings and gun violence.

The State Department is obligated to inform the public about potential threats under a “no double standard” rule that calls for such information to be shared equally with government employees as well as the public.
