I don't know what calmer language can be used to describe a potential invasion, other than to keep repeating the facts. The Ukrainian government is facing economic pressures, and there are significant preparations in Ukraine in terms of civilian and defence potential scenarios, as well as with the UN on humanitarian and refugee scenarios.
It is only responsible to forecast the possible invasion scenarios and prepare for them. It would be irresponsible to pretend that the threat is minimized. We could be caught off guard, as we have many other times, by Putin.
