Putin is largely ignoring the expertise of his military advisors, US analysts said in a report. Instead, he is making most of the key decisions on his own, they said. The experts at the RAND Corporation said Putin has proved more cautious than many expected. Russian President Vladimir Putin is making key decisions about the Ukraine war largely on his own, without input from his generals, analysts said in a report published last week.

But while doing so, Putin has proven to be more cautious than expected, said the report from the US-based RAND Corporation.

"Putin [is] making key decisions largely on his own without substantial influence from the Russian General Staff," the analysts said in the report.

RAND said that was simply because Putin does not trust those around him — and so makes "little use of economic or military expertise" at his disposal.
