Let me simplify it for you.
This is an escalation by the Ukraine.
Russia will escalate in response.
Russia has the ability to escalate far beyong the level of Ukraine.
You consider a sovereign country fighting against an invader to be “escalating” a conflict by these actions? What do you consider their duty is, to just bend over and take it?
“Russia has the ability to escalate far beyong the level of Ukraine.”
***Which is why the Ukraine is asking for help from everybody. The last time a regional tyrant bully invaded his neighbor over oil & gas rights, an international coalition kicked his ass back to Iraq. Similar thing is happening here, just more piecemeal.
