> But, it doesn't break any treaties that Russia signed with Ukraine in the last decade
I don't think that's true. In fact, I think in the last decade (or, 11 years), the russians have done this ~25 times.
A standard russian tactic appears to be to ask the enemy to lay down their weapons, and then when the soldiers comply, the russians shoot them in the face anyway.
Those are slightly different things than treaties (as the articles you quote show, many of those ceasefires were unilaterally declared by Russia, not the result of an agreement between the two parties). Still, I don't mean in any way to praise Russia here, or even to claim that the USA is just as bad as Russia on this.
As bad as many of the US unilateral cancelations of treaties I mentioned are, they do not in any way compare to the horrifying aggression that Russia is showing in Ukraine, both at the basic level of invading a neighbor to steal their land, and in the details of how they are pursuing this illegitimate goal. Putin and his general are war criminals to a degree that few others in the last decade could be described (Netanyahu and Assad probably being the main "competitors", and Assad was only able to do what he did with Putin's help).
