(CNN) - On the same day Vice President Joe Biden knocked Mitt Romney for having a "Cold War mindset," two of Romney's national security advisers made references to threats dating back to the Soviet Union era.
Attacking the Obama administration for "withdrawing in leading the free world," former Navy Secretary John Lehman argued on the call that the president's policies open the nation up to "huge new vulnerabilities."
"We are seeing the Soviets pushing into the Arctic with no response from us. In fact the only response from us is to announce the early retirement of the last remaining ice breaker," Lehman said.
Also, in a discussion on the new Strategic Arms Reduction Treaty (START) with Russia, former U.S. Ambassador-at-Large for War Crimes Pierre Prosper mistakenly referred to a country that no longer exists.
"You know, Russia is another example where we give and Russia gets, and we get nothing in return," he said. "The United States abandoned its missile defense sites in Poland and Czechoslovakia, yet Russia does nothing but obstruct us, or efforts in Iran and Syria."
Czechoslovakia split into two countries–the Czech Republic and Slovakia–in 1993.
Neither country served as a site for the proposed U.S. missile defense system. The U.S. wanted to put part of the system in the Czech Republic, but the country's prime minister canceled a vote in 2009 that would allow the move to take place.
Later that year, the Obama administration decided to scrap the plan in Eastern Europe, which was first proposed by the Bush administration.
The advisers' remarks came after Romney's campaign has had to beat back consistent attacks targeting the candidate as out of touch on matters of foreign policy. The criticism largely stemmed from Romney labeling Russia as the United States' "number one geopolitical foe" last month.
Team Romney did not immediately respond to a request for comment.
