U.S. military is worried about China and Russia developing hypersonic missiles. These are missiles that can travel between five and twenty times speed of sound. Both Russia and China are developing the missile lot faster than United States. senior U.S. military official said this could be security problem for USA. General John Hyten warned that USA has no defense that could stop use of such weapons against it. He said USA needed small nuclear weapons to stop Russia attacking USA. President Donald Trump said he has "plans to get together in not-too-distant future" with Russian President Vladimir Putin to discuss arms race.
Russia says it successfully tested hypersonic missile earlier this month. China tested its missiles last year and will soon have weapons ready for use. President Putin explained that Russia needs weapons because of actions other countries have taken against it. He said "unlawful sanctions" by USA and European countries have hurt Russia's development. He added: "You have failed to contain Russia." Mr Putin says missiles will be able to fly anywhere in world and will "strike like fireball". Tensions increased this week after USA and many European countries expelled Russian diplomats after reported poisoning of Russian spy in England.
