The row amonge Russia and Nato has rise up. US Defence Secretary Ash Carter has accused Russia of “nuclear sabre-rattling” and of being intent on eroding international order.
He said he regretted strained relations with Moscow but said the US had to “prioritise deterrence” on Nato’s eastern flank.
Speaking during a ceremony at the US European Command Headquarters in Germany, Carter said Russia was “going backwards in time”.
But Carter said: “We do not seek a cold, let alone a hot war with Russia.”
“We do not seek to make Russia an enemy. But make no mistake, we will defend our allies, the rules-based international order, and the positive future it affords us.”
He added: “Moscow’s nuclear sabre-rattling raises troubling questions about Russia’s leaders’ commitment to strategic stability, their respect for norms against the use of nuclear weapons, and whether they respect the profound caution that nuclear-age leaders showed with regard to brandishing nuclear weapons.”
Carter outlined plans to deploy a third US Army combat brigade in Europe in the coming year.
He said it was part of a $3.4bn (£2.3bn) initiative to reassure Nato allies of US commitment to their security and to deter Russian aggression.
“We haven’t had to prioritise deterrence on Nato’s eastern flank for the past 25 years, but while I wish it were otherwise, now we have to,” he said.
The tensions has risen since Russia’s annexation of Crimea and its role on Ukrainian civil war. Last month, two Russian fighter jets flew close to US warship on Baltic sea.
Russia’s envoy to Nato said the destroyer had sailed close to the Russian enclave of Kaliningrad in an attempt “to exercise military pressure on Russia”.
Conclusion: The trouble ties between Russia and US.
