I currently cannot access the NYT articles, which are paywalled. You are correct that there is no link given for this claim.
As for the terrorist attack, it is defined in numerous ways, Oxford for instance defines it as "the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political aims."
Is the bridge in Crimea used for civilian purposes in addition to military ones? Yes.
Is it a legitimate target? Sure. Was it a smart action to do this? I don't think so, look at the results of such actions. This much was predictable.
Of course, there is no doubt that Russia is committing, by far, the most terrorist attacks in Ukraine, it's not even a competition.
the US, along with almost every other country in the world, considers Crimea to be part of Ukraine, not Russia. And the phraseology, such as "pumping Ukraine full of the world’s most advanced weapons systems" (накачка украины оружием - google this phrase) is straight from Russian propaganda playbook — SophistiCat
You are right. On the other hand, it is
de facto taken to be part of Russia. Obama applied the mildest of sanctions when the Russia annexed Crimea. It has important military value for Russia, given the naval base they have there.
I don't think this area will be given back. The newly annexed territories are a different matter, this was a desperate attempt to save face given the counterattack.
The quoted phrase may indeed be out of the Russian propaganda playbook, but it is no less true for being so. You think Ukraine would've lasted much without such help?
I happen to think that the longer this lasts, the more civilians will die, which is not good for Ukraine by the way.
