The political problem we face here is that Lukashenko (Belarus) would not act like this without some sort of "approval" from Putin.
Whatever we think we are watching here now, could be the pre-text for a future invasion / annexation of the Baltics. This has always been one of Putin's long term goals, reunite the old Soviet states.
What happen after MH17? Not a lot.
What happen after invasion of Crimea, not a lot.
What happen after the UK poisoning attempts, not a lot.
Can we see a trend here now?
Putin has without being directly involved tested the waters, and watching the the re-action, or should we already now predict there will be complete in-action from either ICAO, EU or NATO, as nobody really wants to poke the "bear".
If only Belarus had oil like in the ME, the rest of the world would be truly outraged, instead we remain on the merry go around, trying to keep the bear content, so it won't attack us.
First action should be stopping Nord Stream 2, dependency on Russian energy, how dumb can you really be within Europe?
Russia are playing their "war games" with both Europe and UK, knowing they are all talk without a bite. It is embarrassing to watch, and having Trump for 4 years did not exactly help as he was clearly in some debts to Putin.
