The White House said Putin confirmed what the U.S. has already known: that Russia has been developing “destabilizing weapons systems for over a decade in direct violations of its treaty obligations.”

Spokeswoman Sarah Huckabee Sanders said President Donald Trump understands the threats and that America is “moving forward to modernize our nuclear arsenal and ensure our capabilities are unmatched.”

Pentagon spokeswoman Dana White also said the Defense Department wasn’t surprised, adding that the U.S. military is prepared to defend the nation.
Kremlin spokesman Dmitry Peskov denies White House spokeswoman Sarah Sanders' claim that Russia breached any international arms control pacts, after President Vladimir Putin's March 1 speech on nuclear weapons.
