Johnson supported the US-Ukraine minerals agreement: It is extortion, but there are positive aspects According to him, signing this document is the only way to move forward in ending the war. The former British Prime Minister noted that he had seen an updated draft of the agreement, which now allegedly obliges the United States to support a free, sovereign and secure Ukraine. “I look at this document and see positive things for Ukraine. I think it contains seeds of hope and progress,” Boris Johnson said.
