Who might not think they are, the people they are invading?

If it's a fight over the Ukraine they likely feel that NATO (us) inspired the whole thing and that we have no business there. I didn't mean to say that Russia will invade Poland or wherever - that is falderoll. But a fight over the Ukraine could escalate - one side gaining ground...the other gaining it back...and then you have a ground war with neither side thinking they are the "invaders"...and that's when it could get ugly.

That would be a lot of confusion to forget whether the Russians are invading you or rescuing you from yourself.

Generally speaking, an “invader” is a foreigner with the intent to occupy or control another country.
