I'm reading the wordreference.com definition of invasion [http://www.wordreference.com/definition/invasion] and turns out some meanings don't imply an open hostility towards the "invaded".
What if the aliens come in peace, but decided to land on earth without us inviting them? That qualifies as an invasion, but they have no hostile intentions.
I would personally wait until the first shots are fired.
