Yes. We're trying to kill the "evil doers". Extreme, would be going "hey, [censored] it, they let terrorists in their nation, we should just lump them all together and kill them all."

So your saying moderate equals the invasion of two countries and not killing the civilains only the "evil doers" (lol)of that country, and extreme equals invading a country and killing everyone man women and child.

Well if your scale slides that far than yes the invasions are moderate, but in the real world the latter options are just ridiculous if not insane, therefore the invasions of Iraq and Afghanistan are both extreme if the word is to have any real world relevance.
