'Right' is not a question in international politics. Only force is. Russia's military might is greater than its economic might, so it will use the military where Washington would like Ukraine to be nominally independent and subject to its economic pressure.

Regardless, many states have had an existence before 1917. Poland, for example. Egypt goes back to ancient times. Ukraine, never. It is an invented state, which is why I will not mourn its passing (particularly since it is serving the interests of Drag Queen imperialism), though I do hope that there will not be a great deal of bloodshed.
