Why does Canada need an aircraft carrier?
I don't know, but our government seems to love to buy the old things of the British Army.
You know, that is a way for spending less money.
Military spending is not very liked in Canada, so, government often used things than others armies don't want anymore.
Harper is contested in Parliament by the opposition because he decided to buy brand new planes! It is too expansive, according to them.
True, buying submarines which are taking fire and helicopters which are crashing was so a good idea, when opposition was in power. Especially than most of the money was going to repair them and to make up for their absences for all the "unexpected" mechanical problems...
