Stephen Harper is is looking to double the Canadian Defense budget over the next 20 years.
While there are doubtless some needs driven by the wear and tear from operations in Afghanistan that need to be addressed, this proposal is far more ambitious, calling for extensive upgrades in weapons systems capabilities, most of which have very little correlation to any future needs, which would be in a peacekeeping/counterinsurgency scenario, where legacy systems with communications and networking upgrades could meet the needs of the conflict just as well as new equipment.
In all fairness though though in a counter insurgency scenario the roughly 10% increase in force size may make sense.
We already know that Mr. Harper is very much of the Western Province (Alberta) tradition, which by Canadian standards is rather wingnutty, so I wonder how much of this is driven by a real need to upgrade forces, since any foreseeable conflict would resemble Afghanistan, where the existing systems are more than adequate, and how much is an attempt to pre-allocate money so it won’t be available for things like the national health service and public education.
There is also a 3rd explanation, which is that if there is a common thread among right wing parties world wide, it is a fetish among the about the creation and maintenance of large military establishment, even when threats do not justify this.
It may also be a combination of all three.
