He continued, "The time for cranking up the antiwar machine is right now".

Google chief Sundar Pichai said Dimore "crossd the line by advancing harmful gender stereotypes in Google's workplace". Several conservative activists have criticized Damore's firing, and some groups have called for a Google boycott.

National security adviser H.R. McMaster on Sunday defended President Trump's escalating rhetoric directed at North Korea and said that he does not believe that the United States is any closer to war than it was a week ago. I mean, we're not North Korea, thank God.
McMaster said that Trump "made clear that the United States will not tolerate our citizens or our allies being threatened by this rogue regime". "Hopefully, Kim Jong-un will find another path!" And we're working on other things, including infrastructure.
"If he utters one threat in the form of an overt threat", Trump told reporters, "if he does anything with respect to Guam, or anyplace else that's an American territory or an American ally, he will truly regret it, and he will regret it fast".
