This week, Russian President Vladimir Putin meets with U.S. Secretary of State Rex Tillerson in Moscow; thousands of Venezuelans protest in the streets of Caracas for nearly two weeks; China orders a fleet of North Korean cargo ships carrying coal to return to North Korea because of that country’s repeated missile tests; and more.

Representative Ted Lieu explains why it is absolutely critical that the United States address the connections between climate change and national security.

This week, the Assad regime carries out a chemical attack in a rebel-held Syrian province, leading to a U.S. military airstrike; an explosion in a subway in St. Petersburg kills 14 people; North Korea fires a ballistic missile into the Sea of Japan on the eve of first meeting between U.S. President Donald Trump and his Chinese counterpart Xi Jinping; and more.

Ira Kasoff writes that if President Trump's tweets and executive orders are a guide to what we can expect during this week’s U.S.-China summit, the two countries could be in for a contentious meeting.
