Answer:
United States
Explanation:
Are you sure your question is worded right?
Are you sure it wasn't asking for the North Eastern country? If so, here's that answer.
That would be the United States! Russia is a massive country and spans the northern portion of Eurasia reaching from eastern Europe to the Kamchatka Peninsula in northeast Asia. That peninsula is bordered by the Bering Strait, the body of water that separates Russia from the State of Alaska.
As far as a threat, North Korea has been seen as such for many years (since WWII), when North Korea sided with Russia. America and its Capitalism were not fond of the Communist party, and so we have really been fighting/being concerned about Russian influence.
Historically North and South Korea have been in conflict many years before America and Russia got involved. When we did though it got worse.
Trump has done very little to resolve this, some would say he is making it worse.
AND as for any current events ask Google!
