Would I Lie To You?

If it came down to a game of 'Would I Lie To You' between Russia and the United States it would be a tough call because both are about as honest as the day is long, a day on Jupiter that is. 
Both are pointing the finger at each other in the latest round of 'you-did, no-you-did' as Russian jets buzz American planes in the region.
The Americans are saying the Russians acted in an 'unsafe and unprofessional manner' after a Russian SU-27 fighter jet intercepted a US aircraft approaching its border.
The Russians replied that the American planes were turning off their identification transponders and flying towards Russian airspace.
'The US Air Force has two solutions, it can either not fly near our borders or turn the transponder on for identification' shrugged a burly looking Russian.
The Pentagon said its Air Force RC-135 plane had been flying a routine route in international airspace when it was intercepted.
Who to believe? On the one hand the Russians have been doing to Britain exactly what they have accused the Americans of doing and flying towards British airspace without identification before turning away sharply while America, well, you would be crazy to take anything that comes from their military at face value so its like a bun fight between a used car salesman and an estate agent, you can't believe either.
