Reuters, citing four sources, revealed that officials in the US Department of Defense (Pentagon) have asked several NATO member states in recent weeks to reduce their rhetoric regarding the threat posed by Russia on the pretext that some statements published by European leaders and officials undermine the continent's security. The sources, who asked to remain anonymous, said that Lithuania, Latvia and Estonia are among the countries that have received letters urging them to control their public statements. It was not clear whether these announcements, made during bilateral meetings, were received by other European governments. The US claims come as the Donald Trump administration revives its efforts to negotiate an end to the all-out war in Ukraine, which has entered its fifth year. In response to a request for comment, a Pentagon official said: "Private conversations between allies are private conversations, so we will not respond to these allegations."
