canada's muslim and arab population dwarfs it's jewish population by several orders of magnitude, is more inclined towards conservative value systems than north american jews (who tend to lean left...) are and is likely not statistically less wealthy (although it may have less ultra-wealthy people). canada is better than the united states in limiting campaign donations. from a domestic political perspective, it is entirely irrational for the conservatives to blindly support israel at the expense of alienating a larger arab vote that's more inclined towards it's policies.

i think the truth is that harper is an evangelical christian of a particularly fundamentalist type. i think it's a personal conviction, brought out by a complex interaction between his religious beliefs and being raised in an environment where the second world war never really ended. i think, in his mind, nato is still fighting to save the world from evil, and supporting israel falls into that narrative for whatever reason.

you have to understand that it's widely recognized in canada that stephen harper is not mentally well - he is at the least a clinical psychopath, and has shown multiple symptoms of various personality disorders. it's not always wise to try and understand him using the "rational thought" model. he is constantly behaving erratically.
