In a last ditch attempt to save the Intermediate Nuclear Forces (INF) Treatywith the United States, Russia has taken the unusual step of putting their new missile, the 9m729, on display for foreign audiences to inspect. 

The US has accused the Russian missile of violating the INF, though Russia maintains that this is not the case. The missile is on display at a military theme park on the outskirts of Moscow.

At issue is the maximum range of the 9m729. Russia says it has a maximum range of 480 km, and testing was broadly at the 400 km range. The INF would forbid the missile if its range exceeds 500 km. The US has argued that they believe the missile has a longer theoretical range, and is therefore in violation. 

US diplomats were also quick to condemn Russia for the public display of the missile, declaring it "insufficient" to comply with US demands. The US had demanded Russia either scrap all such missiles systems, or hand them over to the US  to be dismantled and tested by American forces.
