MOSCOW: Russia on Tuesday successfully test-fired a next generation intercontinental ballistic missile capable of piercing the planned US missile defense shield in central Europe.

After the demise of the USSR,uncle sam was the only surviving superpower,and had been roaming the world unrestricted,like a rampant elephant(or may be rabbit;) )
The Russians have now revived their military capabilities and the sleeping tiger has started to flex it's muscles.
In their hay days,they were far ahead of USA in space and missile technology.All this in effect kept a nice balance in the world politics.
Russians have gladly started to act as a super power again,and so uncle sam will find a worthy opponent to keep himself busy,and will not have to dig holes in Iraq or lose men in the afghan caves,to keep his war machine lively.
