Buy European

Yeah but the goal of that Ketchup War wasn't to boycott the US, just to ensure that ketchup was being produced in Canada. And it was successful as Heinz was forced to open a new plant in Canada.

Now I just get the store brand Ketchup (seems good enough to me, it's likely made in the same plant as French's) so I think the US is completely out from my Ketchup purchases. Though I'm not sure who owns that plant (it's not French's they just have a contract with that plant to make it for them) but the point is to reduce the amount of money going to the US as much as possible, and that'll do it.
