The Kremlin and the World - Part Four

Almost two decades have passed since the end of the Cold War but it seems like an unexpected chill has hit world relations.

In this four part series, Tim Whewell looks at the recent conflict of issues that could re-draw the old fault lines that once divided East and West.

Russia has fallen out with its western counterparts over the murder of former spy Alexander Litvinenko.

There are also fears about energy supplies and talks of a new arms race.

Allegations of spying against the US and UK have decreased the chance of negotiation even further.

Could a new confrontation with Russia be on the horizon?

With the Russian presidential elections approaching in March, Tim speaks to Kremlin insiders and key players in Europe and America.

He finds out what has gone wrong and why it has become so hard to dance with the Russian Bear.

Part 4 - The Bear Unbound

In less than a decade Russia has become known for its vast energy reserves and blossoming economy, fuelled by income from its vast natural resources.

However politically, Russia seems to be harking back to the days of the old Soviet Union and playing by its own rules.

In the fourth part of the Kremlin and the World, Tim Whewell finds out where this new East, West confrontation is heading.

In April last year, history came tapping on Estonia's shoulder - an old quarrel with Russia was about to be pursued by the most modern means.

Estonia believed that the Russians were behind a cyber attack which temporarily paralysed their computer network.

They say the attack began after it moved a Soviet war memorial in Tallinn.

Russia has also fallen out with Georgia, Britain and America and it seems like both East and West are reverting back to old stereotypes.

Has the bear has finally crawled out from its lair? Tim finds out if we should be worrying now that the Russian Bear is definitely back.
