Yes we do already do coordinated bombings (well not Canada anymore woo) but we still see more civilian casualties than terrorist ones, which is part of the decision to stop air strikes being sent from Canada
The solution is not as easy as just air striking, yah civilians will die regardless and it's a casualty of war we can't avoid but the civilian deaths to date greatly out rank the terrorist ones, so before they do more coordinated bombings they should fix the ones they already have in place
You need to look at it from both ends of the spectrum, trying to kill the terrorists has only made us the terrorists
