Trump’s about-face on Russia

• President Trump rejected new sanctions on Moscow on Monday, a day after the U.S. ambassador to the U.N. said that Washington would impose penalties on Russian companies that helped Syria’s chemical weapons program.

By overruling his advisers, Mr. Trump highlighted what analysts say is an inconsistent strategy toward Russia. He says he wants a good relationship with President Vladimir Putin.

In Britain, Prime Minister Theresa May defended American-led airstrikes on Syria but was accused in Parliament of acting on “the whims of the U.S. president.” Weapons inspectors hoping to assess the site of a suspected chemical attack near the Syrian capital were denied access.

• Separately, the U.S. and Britain warned of possible cyberattacks from Russia involving internet routers in homes and businesses.
