The comments -- made at the end of a summit between Russia and European Union that failed to resolve several festering disputes -- were the latest in a series of belligerent statements from the assertive Putin.
Emboldened by oil- and gas-fueled economic clout, Russia is increasingly at odds with Washington and much of Europe on issues ranging from Iran and Kosovo to energy supplies and human rights.
Putin used a news conference at the summit's conclusion to reiterate Russia's stalwart opposition to U.S. plans to put elements of a missile defence system in the former Soviet bloc countries of Poland and the Czech Republic -- both of which are now NATO members.
"Analogous actions by the Soviet Union, when it deployed missiles in Cuba, prompted the 'Caribbean crisis,'" Putin said, using the Russian term for the Cuban missile crisis.
"For us the situation is technologically very similar. We have withdrawn the remains of our bases from Vietnam, from Cuba, and have liquidated everything there, while at our borders, such threats against our country are being created," he said.
The October 1962 crisis erupted when President John F. Kennedy demanded that Soviet leader Nikita S. Khrushchev remove his country's nuclear missiles from Cuba because they could have been used to launch a close-range attack on the United States. The Americans imposed a naval blockade on Cuba and the world teetered on the edge of war before the Soviets backed down.
Putin also suggested that the tension was much lower than in 1962 because the United States and Russia are now "partners," not Cold War enemies. His relationship with President Bush, Putin said, helps solve problems, calling him a "personal friend."
The Russian leader said there has been no concrete U.S. response to his counterproposals for cooperation on missile defense, but added that the United States is now listening to Russia's concerns about its plans and seeking to address them.
In Washington, White House press secretary Dana Perino underscored those remarks rather than the Cuban missile crisis analogy, saying "there's no way you could walk away without thinking that he thinks that we can work together."
The U.S. plan is part of a wider missile shield involving defences in California and Alaska which the United States says are to defend against any long-range missile attack from countries such as North Korea or Iran.
Russia strongly opposes the idea, saying Iran is decades away from developing missile technology that could threaten Europe or North America, and it says the U.S. bases are aimed at spying on Russian facilities and undermining Russia's missile deterrent force.
State Department spokesman Sean McCormack told reporters there were "clear historical differences between our plans to deploy a defensive missile system designed to protect against launch of missiles from rogue states, such as Iran, and the offensive nuclear-tipped capability of the missiles that were being installed in Cuba back in the 1960s."
"I don't think that they are historically analogous in any way, shape or form," he said.
Turning to his future, Putin said he would not assume presidential powers if he became prime minister after finishing his term next May.
Putin is barred from seeking a third consecutive term in the March 2008 presidential election. But he suggested this month that he could become prime minister, leading to speculation that the substantial powers now invested in the presidency might be transferred to the prime minister.
"If someone thinks that I intend to move, let's say, into the government of the Russian Federation and transfer the fundamental powers there, that's not the case," Putin said. "There will be no infringement on the powers of the president of the Russian Federation, at least while it depends on me."
After repeating his insistence that he does not intend to change the constitution in order to run for a third term, Putin said he had not yet decided where and in what capacity he would work as former president. He is expected to remain an influential figure in Russia.
Putin will lead the ticket of the dominant United Russia party in December parliamentary elections. An overwhelming victory for the party could turn the legislature into a new power base for Putin and give him a claim to continued authority based on his popularity.
Putin traveled to Portugal, which holds the EU's rotating presidency, for talks with leaders of the 27-nation bloc. But despite a positive spin put on the meeting by Putin and EU President Jose Manuel Barroso -- who called it "open, frank and productive" -- the summit yielded no major breakthroughs.
The EU and Russia have been without a new cooperation agreement for more than a year, during which time doubts have grown in many European capitals about the reliability of Russia's energy supplies and trade policies toward EU member nations, such as Poland.
Topping the list of concerns is Russia's energy policy -- the reliability of supplies and the intentions of state-run oil and gas companies. Russia already provides 30 percent of EU energy imports, including 44 percent of natural gas imports.
The state-controlled gas giant OAO Gazprom has recently moved to acquire assets in Europe and strike bilateral deals with some EU countries.
That has led the EU to consider new restrictions on non-EU companies owning majority stakes in gas pipelines or electricity power grids without additional agreements -- much to the Russians' consternation.
Earlier, Putin tried to assure European leaders that Russian investment was not to be feared.
"When we hear in some countries phrases like, 'The Russians are coming with their scary money,' it sounds a bit funny," he said.
