"okay, all invasions are wrong"
"Wait if all invasions are wrong, then even border disputes are wrong, and so conflicts over territory are wrong"
"okay, conflict over state 'territory' is immoral"
"Wait wait wait, if you say that ALL state conflict over territory, then the violent enforcement of borders is wrong"
"okay, border enforcement is wrong"
"Now we're really off track: if enforcing borders is wrong then state control of lands is wrong, and states need to control lands and territory to enforce property"
"okay, the ownership of land is wrong"
"So you're saying that no one should get a piece of paper saying they own property? That charging rent and violently enforcing ownership is wrong? Gosh that would mean the whole state system was based on immoral feudal concepts, that it's a preservation of an oligarchy that has sin at its very core!!"
"okay."
