Washington, May 30 (RHC)-- U.S. President Donald Trump has returned to the United States after his first foreign trip as president, where Trump faced condemnation from U.S. allies for his failure to commit the United States to fulfilling its pledges to the landmark 2015 Paris climate accord. 

German Chancellor Angela Merkel, speaking after contentious meetings at NATO in Brussels and a G-7 meeting in Italy, said that talks with the U.S. president were "very unsatisfying." 

The German foreign minister went even further, saying of Trump: "Anyone who accelerates climate change by weakening environmental protection, who sells more weapons in conflict zones and who does not want to politically resolve religious conflicts is putting peace in Europe at risk." 

Meanwhile, French President Emmanuel Macron has said he was trying to convey a deeper significance to his long, clenched, white-knuckled handshake with President Trump in Brussels, saying it was "not innocent" and that "we must show that we will not make small concessions, even symbolic ones."
