Some time ago, the Ottawa Citizen's Defence Watch blog published an editorial by Kyle Meema on why the Saab JAS-39 Gripen would be a great replacement for the CF-18 in Canada. You can read it here: Part One and Part Two.
Mr. Meema has returned to the Ottawa Citizen, this time making a case against the F-35 Lightning II for Canada. You can read the three part series here: Part One, Part Two, and Part Three.
Here is the article, in its entirety, courtesy of Mr. Meema.
