I can answer your question better if you rephrase it.Do you mean what threatens Polar Bears or what kind of threats they have to us?If you mean what threats do they have to us then ...they have the same threats as another kind of bear. If you mean how do we threaten well there is an endless list.We threaten just be entering their territory.Global Warming and Testing also threaten them.
The US bought Alaska from Russia in 1865. There were not any threats against it.

threats of another war
so what it is is you are looking here for nothing
The US countered Soviet threats to free nations by establishing the Marshall Plan and running the Berlin airlift. The US also established NATO, opposed the Korean War, and established the Truman Doctrine.
Grave threat and Light threat are just the same. They are both THREATS to people in terms of Human Rights but these threats will lead us to Bomb treats. Furthermore, if you are going to threat somebody, you must know first the things to be done and must empathize it.
