It seems that you have "transformed" this thread into a blame thread but I don't want to argue with you (it is not a personal thing, here or am I wrong Wink?). Yes that (the example) is a type of invasion as you can read here:

• An instance of invading a country or region with an armed force
• An incursion by a large number of people or things into a place or sphere of activity
• An unwelcome intrusion into another’s domain
