They already were at war with Noxus, they won
But it is true, they'll show you their peace, then beat you mercilessly until you accept it
I mean actually attacking another city state, not defending their own island.
True... Then again, their would be no war
Once the people see Zed, Irelia and Master Yi
White flags would be instant
Allow me to show you an accurate representation:
Gets stabbed by four blades on the battlefield "Fucking nerf Irelia" Dies
See, shen? this is how you spread peace
I thought we had to Stand Uni-
NO. Not that nonsense again.
Don't make me go all Wuju on you again.
You guys suck.
Thank you.
They didn't win :/
They lost but "somebody" rito needed them to win so they got a rematch...
Sorry I used to main darius so I still have prejudices.
Also nearly every Ionian champion is pure cancer 
I wanted to prove you wrong but then I looked at the Ionian champs and needed to agree
Yi lee shen kennen akali syndra zed irelia jhin and karma. Am i missing anyone?

Raka is from the stars and ahri is from elsewhere. Did they both settle down in ionia?
Yeah they both count as Ionians
Ok cool thanks for the info.
?
Then the retcon happened. Ionia is still losing.
I'd like to remind you, that Noxian invasion on Ionia was retconned and is still on-going.
Assuming Riot won't retcon Ionia to have an enslaved god on their side, Noxus will win.
