A former U.S. ambassador to Russia stated that Putin's actions indicate he has not stopped his path towards war.

• According to Michael McFaul, a former U.S. ambassador, evidence points to Putin increasing his troop presence along Russia's border with Ukraine.
• McFaul, now director at the Freeman Spogli Institute for International Studies, stated that there is no evidence to suggest that Putin has halted his progress towards war or reduced his readiness for it.
• Putin's isolation and lack of communication with his advisors have created uncertainty about what will happen with Ukraine, according to him.

A former U.S. ambassador to Russia stated that there is no indication that Russian President Vladimir Putin will cease his aggression towards Ukraine, despite recent discussions with world leaders.

According to Michael McFaul, director at the Freeman Spogli Institute for International Studies, there is no evidence that Putin has halted his progress towards war or reduced his readiness for it.

He is continuing to increase his military strength along all borders and from the water, targeting Ukraine, according to what he told CNBC's "Squawk Box Asia" on Monday.

For several months, Russian troops have gathered near the border with Ukraine, causing apprehension that Moscow might repeat its 2014 annexation of Crimea. Russia has refuted these claims.

Recently, the Kremlin has increased its military buildup at a faster pace, according to White House national security advisor Jake Sullivan.

Russia may fabricate an attack by Ukraine as a pretext for invading its neighbor, according to previous statements from the United States.

McFaul stated that false flag attacks are a "good tactic" employed by Russia and are not novel. Despite Moscow's denial of the accusations, he considered the warnings from the U.S. to be "credible."

The declassification of information by the Biden administration is impressive, as it is difficult to declassify, indicating its credibility, according to him.

Uncertainty

No one knows what will happen next in Russia-Ukraine tensions or how Moscow will respond to sanctions from the U.S. and the West, according to McFaul.

He stated that he believed there was a great deal of uncertainty at present, and that it was uncertain whether anyone knew the answer.

The Russian leader is "isolated," he stated.

McFaul stated that Putin is isolated even in his own country and rarely talks to advisors, which makes it difficult to determine what he is thinking.
