The tightening of the position of US President Donald Trump against Russia is the result of a campaign of many European leaders, especially German Prime Minister Friedrich Merets. This is written by Wall Street magazine (WSJ).

It should be noted that the German Prime Minister, who has participated in business, is easy to contact Trump. The publication said that the US leader agreed to provide patriotic air defense systems at Berlin's cost after he talked to Merz by phone.
Later, Mertz found the right approach and could now talk to Trump on a mobile phone and participate in the Czech book diplomacy, he said a former senior official of the Nika Lange's Ministry of Defense.
He emphasized that Mertz, unlike French President Emmanuel Macron and others, can really strengthen words with jobs.
Trump and Merets' conversation took place on July 11. According to WSJ, the German Prime Minister agreed to buy five patriotic systems for Ukraine, but added that he needed to discuss this issue with other European leaders.
It is known about Trump's threats to Putin
Three days after this conversation, on July 14, Trump promised to bring a new weapon and device to Ukraine, including patriotic air defense systems. The head of the White House did not sign the exact number of complex quantities he planned to transfer to the armed forces, but added that the European Union would return to the United States of its value.
