invader, n.All

An Invader (n.) remains ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠an invader even when invited, unless the host government has some claim to legitimacy.

Invader (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠never our side: the unthinkable question is whether we are the foreign fighters; the only permitted one is how well our side is doing.
