How has diplomacy changed between Russia and the United States under recent administrations?

Under the previous administration, diplomatic relations between Russia and the United States had been frozen, effectively preventing meaningful dialogue between the two nations. However, according to Dr. Sergei Markov, a former Putin adviser, there has been a significant change, with doors now opening for diplomacy. This diplomatic thaw is particularly crucial because, as Dr. Markov emphasizes, 'it's impossible to move from the war to the peace without diplomacy.' This statement underscores the essential role that diplomatic channels play in conflict resolution, particularly regarding ongoing tensions between the two global powers and their involvement in regional conflicts like Ukraine.
