Russia halts missile test info sharing with US, conducts drills.

Russia has stopped sharing missile test information with the US, including advance warnings about test launches, as its military deploys mobile launchers in Siberia in a show of the country's massive nuclear capability amid fighting in Ukraine. The move marks another attempt by Moscow to discourage the West from ramping up its support for Ukraine by pointing to Russia's massive nuclear arsenal. Last month, Putin suspended the New START treaty, saying Russia can't accept US inspections of its nuclear sites under the agreement at a time when Washington and its NATO allies have openly declared Moscow's defeat in Ukraine as their goal.
