And at "best", Assange could be the source of the (mis)information that Snowden may have been on board - the stunt itself was entirely pulled by the governments of France, Spain, Italy.
Countries that minutes earlier they were cleared to fly through, and had planned to fly through. Had they ignored the refusal and proceeded as planned? Same ending: fighter jets.
Let’s not pretend here that this is different.
If there was really a dastardly plot to capture the guy that wasn't even on the aircraft, they'd have gone for fighter jets, not "don't land in our country, land in the country you're flying over where a diplomat will be mildly undiplomatic towards you [or fly back to Russia completely unmolested]"
Let's be honest here: Putin and Lukashenko can get away with this sort of shit because "we" first showed that it's acceptable behaviour. This is the risk of breaking unwritten rules on the international stage: sooner or later a bad guy will do it too, and you won't have the moral high ground. This journalist, and all the others who will have to take airspace into consideration from now on, are paying for the sins of Obama.
Apparently the whole thing was a stunt by Julian Assange? Don't know how true that is
Definitely a bit dodgy though
