The British army in Iraq couldn't keep Shia militants out of Basra (their single duty, wasn't it?), nor do anything useful in Afghanistan. Half the French army is deployed to protect Jewish schools and synagogues in France (and the Louvre, let's not forget that). And the German "army" is outnumbered nearly twenty to one by the the young Muslims Merkel invited ito settle in Germany between 20014 and 2015.
...so even against the remnants of the once mighty Soviet war machine with its rusty tanks a "European army" would have a bit of a problem, wouldn't it?
Actually AB does have its own Russian expert Ichkeria. Wonder what he has to say.
