Mike Pompeo has announced the US is suspending its participation from a crucial Cold War nuclear treaty with Russia - triggering fears of a new Cold War-style arms race.
Analysts have expressed fears that an American exit from the Intermediate-Range Nuclear Forces agreement, which banned ground-launched cruise-control missiles when it was signed in 1987, could spark tensions between the old rival superpowers and China, now Asia’s dominant military presence.
The president has meanwhile attacked the FBI's arrest of political fixer Roger Stone and dismissed his recent shutdown talks with Democrats as a “waste of time” in a wide-ranging interview with The New York Times.
If there's no deal by then, President Trump has threatened to revive the shutdown or declare a national emergency, which he claims would let him shift billions from unrelated military construction projects to erecting his wall.

US officials also have expressed concern that China, which isn't part of the treaty, is deploying large numbers of missiles in Asia that the US can't counter because it's bound by the treaty.
The move has sparked criticism in some quarters, however, with former Soviet leader Mikhail Gorbachev – who signed the treaty with US president Ronald Reagan – describing it as “not the work of a great mind".
