"It is unlikely that this choice will change anything in NATO's general policy. At the moment, this is an alliance of enemies for us," Kremlin spokesman Dmitry Peskov said.

The Kremlin's statement came shortly after Dutch Prime Minister Mark Rutte was confirmed as the next NATO Secretary General, succeeding Jens Stoltenberg.

Mr. Rutte will take office next October, in the context of the ongoing war in Ukraine, along with unpredictable forecasts about the US attitude towards this military alliance.

Observers say that Mr. Rutte's main task in his new position will be to balance the conflicts of interest among 32 NATO members so that the organization has a unified voice and especially to solve the "difficult problem" of the Russia-Ukraine conflict.

The problem, however, is that Mr Rutte is often harshly critical of Russian President Vladimir Putin and is a staunch ally of Ukraine.

His views were heavily influenced by the downing of flight MH17 over Ukraine in 2014, which killed 298 people, including 196 Dutch citizens. The Netherlands blamed Russia for the incident.

And Mr Rutte has also caused a stir by saying that NATO must be strong to stand up to Moscow and that other EU leaders "must not be naive" about Russia.
