shooting live rounds into a crowd of (presumably) unarmed or lightly armed (think sticks, stones) protesters is a vile, inexcusable failure or intentional executions to retain the status quo.
A police force with tear gas, water cannons and riot gear has zero reasons to resort to live ammunition.

So, offering support to a sovereign state is not encroaching on a neighbouring state’s borders.

However, annexing a bordering sovereign state is per definition encroaching on another state’s borders.

Even if you do it with unmarked soldiers and officially state it’s totally not you doing it.

Doing the same thing openly, 8 years later with full military force is also illegal.

Correctly predicting an invasion doesn’t justify it.

Reports from the rest of the world:
