While the US administration does not take action, China, Russia and Iran are strengthening alliances and building up forces, he said.

Among other things, Bolton called the withdrawal of US troops from Afghanistan a catastrophic blunder. 

The former adviser urged the Biden administration to take national security policy more seriously. 

He also believes that Biden does not allocate enough funds to modernize the US army.

“We must pull ourselves together, otherwise it will only get worse,” he said.

Earlier, Bolton said that the US should reconsider the number of nuclear warheads and delivery systems against the backdrop of rivalry with Russia and China.

Russian Senator Alexei Pushkov said Bolton's remarks about revising the number of US nuclear warheads are a sign of political madness.
