Putin also said that Russian Federation could easily make and deploy land-based intermediate-range missiles if the United States made good on its threat to quit the treaty.
He also noted that Western analysts are talking about the possibility of using low-yield nuclear weapons.
"The U.S. base on Okinawa has been there for decades now".
"Donald's right and I agree with him", he said at his annual press conference in Moscow on Thursday.
Faced with a rather provocative question from the WSJ Moscow Bureau Chief, Ann Maria Simmons, Putin said that "when it comes to ruling the world we know very well where the headquarters [of those], who are trying to do exactly that", is located.
"You aren't interested, you don't need it?"
Putin suggested the U.S. judiciary was pushing the case through to "save its face", adding that Russian Federation would keep an eye on the legal battle to see what happens next and assist Butina if possible.
Russia's President Vladimir Putin has accused the United Kingdom and USA political classes of "disrespecting" the public by questioning the Brexit referendum and Donald Trump's election. "Lowering the threshold could lead to a global nuclear catastrophe", he said.
"We will have to ensure our security", he said.
He warned of a "collapse of the global arms (control) system" following Washington's announcement it would drop the Intermediate-Range Nuclear Forces agreement.More news: 'Oil producers to review output cut in April'

He had one nice things to say about the United States, however: He welcomed President Donald Trump's decision to withdraw the U.S. military from Syria.
"We will have to ensure our security", Putin said during the news conference that lasted almost four hours.
Butina pleaded guilty last Thursday in front of a United States federal judge to one count of conspiracy to act as a foreign agent. The pullout is also likely to strengthen Russia's role in Syria's future.
Her case is a vivid "part of a larger mosaic of Russian influence operations" laid out in part by special counsel Robert Mueller's probe of Russian interference, former Justice Department officials David Laufman told The Washington Post last week. There is only one aim: "to hold back Russia's development", he said, later lamenting that relations with Britain were at a "dead end".
Putin showed no sign of backing down from Russia's stance on Ukraine, and accused his Ukrainian counterpart of provoking a naval stand-off with Russian Federation to boost his electoral prospects.
Putin reaffirmed the long-held Russian argument that the USA presence in Syria is illegitimate because it hasn't been vetted by the UN Security Council or approved by Assad's government. "They are shooting at their citizens which they believe are Ukrainian citizens".
On the Russian economy, Putin hailed another year of growth after a previous period of stagnation.
Putin said the economy grew 1.7% over the first 10 months of the year, roughly in line with predictions, while unemployment was down.
The Russian president noted that the nation's hard currency reserves have increased from $432 billion at the start of the year to $464 billion now. Full-year growth is estimated at 1.8 percent.
