After fiber-optic cables under the Baltic Sea were cut last month, European officials hurried to stop the Yi Peng 3. It’s still at anchor there, with no update on three nations’ investigation.

As a new reality in Syria sets in, a reordering of regional power dynamics is already taking shape.

Understanding the factors that led to the Syrian regime’s collapse is key to putting the pieces of the country back together.

Nuclear war in space could have catastrophic consequences for life on Earth. President-elect Trump must do everything in his power to prevent it.

Multiple countries are investigating and the authorities in Europe say they have not ruled out sabotage. But U.S. intelligence officials have assessed that the cables were not cut deliberately.

The chairman of the Senate Intelligence Committee said hackers listened to phone calls and read texts by exploiting aging equipment and seams in the networks that connect systems.

President-elect Donald J. Trump is considering nominees who fit more comfortably within his often erratic worldview, in which deal-making reigns over ideology.

The United States can no longer depend on the loyalty of its friends.

Another Trump term could spur Europe’s efforts to stand on its own, but it is far from clear its leaders will seize the moment this time.
