Remind me. Exactly how many enemy aircraft did the CF-18 fleet shoot down the last time Canada got invaded???
The real example to follow is New Zealand:
"Hang on, guys. Do we really need fighter aircraft?"
"Of course! We've always had them!"
"But... erm. Now you mention it. No. Not really."
"New hospitals, anyone?"
"Yeah. OK. Good idea."
Last time I checked, NZ still hadn't been invaded...
