Russia’s Putin issues ominous warning to NATO.

MOSCOW • Russia’s President Vladimir Putin is warning his forces could target NATO sites if the country feels threatened, sharply raising the stakes against the Western alliance even as president-elect Donald Trump calls for greater outreach with the Kremlin.

“We must take countermeasures, that is strike with our missile systems the targets that, in our opinion, begin to threaten us,” Putin said in an interview with American filmmaker Oliver Stone for a documentary broadcast Monday.

The Stone-produced documentary — about the conflict in Ukraine between pro-Moscow separatists and the Western-allied government — premiered on Russian television after advance transcripts of Putin’s remarks were circulated by Russian media.

Putin’s comments were among his sharpest rebukes of NATO as the alliance increasingly focuses on perceived threats from Russia. Earlier Monday, Russia announced it has bolstered its defensive missile strength in the Eastern European enclave of Kaliningrad.

For years, the Kremlin has voiced concerns about the membership in NATO of former Soviet republics and countries from the former East Bloc. Putin said smaller NATO countries would find it “next to impossible to resist pressure from a major NATO leader such as the United States” to deploy missile systems or host new bases.

“And what are we supposed to do? We are forced to take counter measures,” he stressed. “The situation is heating up.”

NATO, meanwhile, has moved to strengthen its presence along its eastern flanks, including the Baltic states. But a major wild card has been introduced by the election victory of Trump, who has suggested that his administration will seek to improve relations with Russia.

“Why are we reacting to NATO expansion so emotionally? We are concerned by NATO’s decision-making,” Putin said.

Hours before the broadcast, Russia said it had deployed mobile coastal defence missiles to Kaliningrad, a Russian enclave wedged between Lithuania and Poland. In October, Putin stationed nuclear-capable cruise missiles in Kaliningrad, further arming a region already bristling with weaponry.

The growing brinkmanship also extends to defences against possible cyberattacks.

Finland’s undersecretary of state, Jori Arvonen, told reporters Monday that a joint NATO-European Union centre is planned for Helsinki to study “hybrid” warfare, including cyberespionage and propaganda via social media.

Arvonen said the planned centre seeks to battle online incursions that could be “diplomatic, military, technological or financial in their nature.”

U.S. intelligence officials suspect high-level Russian involvement in emails hacking targeting Hillary Clinton’s campaign chief and others during the presidential campaign.
