Russian President Vladimir Putin said that deploying US missile-destroying systems in Alaska and South Korea would be a big challenge for his country and Moscow would give its answer by increasing its strength.

Putin said on Thursday in an economic forum in St. Petersburg, "There is no other way in Moscow." He clearly said, "When Moscow is expanding military power at the border between Russia and Europe, Moscow can not sit back and forth''.Putin said in the international media, "Moscow is particularly concerned about deploying US-based missile-deployed missiles in South Korea to address North Korean threats. Moreover, Moscow is worried about the US plan to increase the power of Fort Gilillor launch in Ballistic missile in Alaska''.All these steps are being destroyed by the world's strategic balance. What is happening is very serious and worrying. This is happening now in Alaska and South Korea. The missile-devastating defense system is emerging. Will we see these helplessly? Of course not. We are thinking about how to respond to this. All these steps are challenging for us.
