Has Lavrov ruined his reputation in Putin's eyes?

As journalists managed to find out, it was the tough position of the head of Russian diplomacy during a conversation with US Secretary of State Marco Rubio that became one of the reasons for the freezing of the Trump-Putin summit.

"Lavrov either missed the moment or went off script. His diplomacy—or rather, the lack thereof—derailed the summit and it was a failure," said one insider.

According to journalists, this was a blow to the image of the Russian dictator, who is very keen to establish a dialogue with the Trump team not only on Ukraine but also on nuclear control issues.

It was because of Lavrov's antics that Putin looked weak on the international stage and unable to maintain control over his own minister.

Political scientists point out that for the head of the Kremlin, loyalty and discipline are the most important things.

And if Lavrov has truly "crossed the line," his political career could be over.
