Ukraine troops are still fighting pro-Russian rebels

Not since the Cold War have relations between Russia and the West been more dangerous than they are now.

I dealt with Russia for more than 20 years in the Foreign Office , and served as Ambassador to Russia between 2004 and 2008. So I’m disturbed to see that communication between our military forces is currently close to zero.
Just one incident – an aircraft collision, for example – could escalate conflict immediately.

There is simply no safety net in place any more.
Yes, Russia is a far smaller power than the West, certainly smaller than it was during the Cold War , but because of that, it is perhaps even more dangerous.
