Why should Canada do coalition missions? They have nothing to do with Canada. Coalition missions are euphemism for beating up a weaker country. As far as I can remember, the F-35 in Canada was always argued by those who want to play John Wayne in foreign lands.

If Canada can't defend against the US, then they should just accept they'll be swallowed by it or start making babies and populating the prairies. In the meantime, if Canada wants to contribute to defense of its allies, it should focus on creating a credible air counter to the Arctic.
