Russia’s Ministry of Defense releases videos showing off new hypersonic weapons

Russia's Ministry of Defense released videos on Thursday showing new strategic weapons, most of which the U.S. cannot currently defend against. The weapons displayed in the videos are a significant addition to the Kremlin's arsenal, which already has more nuclear weapons than other countries, according to estimates. The new videos come on the heels of President Donald Trump's meeting with Russian President Vladimir Putin in the Finnish capital, Helsinki.
