Where is the White House pressure on Russia over London poisoning?

Austin, Texas: Deadly poisonings and attacks on Kremlin-linked figures are likely to meet little resistance from the White House, an American defence expert says.

As Cold War-era understandings on permissible spy behaviour unravel, there has been little US pressure to counter Russia’s suspected activities, Georgetown University national security professor Mark Jacobson told Fairfax Media.

“During the Cold War the Soviets were constrained by the threat of a US reaction,” Jacobson said. “Today there is no threat of action by this White House.”
