Even the entry you cite talks about Assange deliberately leaking false info about Snowden onboard. Either way, this is rather poor whataboutism. Landing a diplomatic plane is not threatening to shoot down a loaded civilian jet in order to arrest and most likely now murder a political opponent.
Wow, little bit easier. Shoot down the plane? Murder a political opponent? I won't really comment that nonsense.
As for Evo Moralez incident, the head of the State and its stuff has diplomatic immunity. Even if the plane is packed with snowdens and assanges you can NOT touch it.
