Considering that Crimea seems to take a cruise missile or two every month and we know that the Ukrainians have done a cross sea raid on Crimea.
How is it a new theatre? its already one.
The day things started going boom in Crimea is the day it became a theatre in the war, and that was a long time ago.
Your assumptions regarding the ethnicity and makeup of the Crimea are straight from Russian propaganda attempting to soften the perception of their actions.
I can tell you with complete confidence we do not view the Crimea as “an outlying dependency”. It was as if Canada had crossed the border into the US and taken a state.
That is the same thing they tried to do to Kiev more recently. Take it quickly and without a fight.
If that had succeeded, would we say Ukrainians have no right to "escalate the conflict" by trying to throw Russians out of Kiev? Would Musk help Russians in that case too?
How do you escalate a conflict where you're being invaded and the invader not only denies your right to exist but also is adamant in committing genocide to remove you even from history books?
