Where are we heading?

[Mr_Moore]

The tone between Russia and the US has been very fierce lately. Russia is poring money into their military. The top countries are maintaining and developing their nuclear devises. If i remember correctly, these countries agreed to decrease the number of warheads. Instead, we are seeing the opposite.
Are we going to face another power battle in the near future between these two countries and perhaps even china?
Putin openly, a few months ago, shared his opinions about the American double standard. His opinions where very critical which itself it amusing seeing where that opinion is coming from.
What country is the biggest threat towards world peace today? How much longer is US going to maintain their position as world police?
