At the annual National Prayer Breakfast this week, President Donald Trump complained that the United States is taken advantage of by virtually "every nation in the world." His administration directed that sentiment at several allies in its second week in office.

The White House claimed Germany manipulates its currency, warned Mexico that U.S. troops could enter the country, and abruptly ended a phone call with the leader of Australia — though Trump denies the latter.

Germany

Peter Navarro, Trump's choice to lead the National Trade Council, reiterated to the Financial Times this week that Germany is "one of the worst actors in the international environment" in the way it manages value-added taxes. Navarro, who also made the assertion to CNBC last week, claimed Germany was undervaluing the euro in an attempt to gain an advantage over other EU countries and the United States. Germany is one of the top five U.S. trading partners, accounting for 4.5 percent of total U.S. trade in 2016, according to the Census Bureau.

Mexico

In a phone call with Mexican President Enrique Pena Nieto on Jan. 27, Trump threatened to send U.S. troops into Mexico, accusing the Mexican president of not doing enough to stop "a bunch of bad hombres down there." "I think your military is scared," Trump said, The Associated Press reported this week, saying it had obtained a partial transcript of the conversation. "Our military isn't, so I just might send them down to take care of it."

Trump did not identify the "hombres" or what makes them bad. The Mexican government subsequently denied the conversation was adversarial in tone. Trump recently inflamed U.S.-Mexico tensions after repeating his campaign promise to build a border wall between the two countries. Mexico is the third largest trade partner with the U.S., accounting for 14.5 percent of total trade in 2016.
