He stated what his strategy was going to be before he got the job and he's doing it. He was going to reinforce other friendships and work on moving our trade away from being so US dependent, and until the US started treating us with respect we weren't speaking to them.
Piss baby will probably be a piss baby about it, but tariffs were going into effect on April 2nd regardless, so there's no reason to engage him if that's a done deal. The variable is going to be how much pain the US can actually inflict on us vs how much the population is willing to take before enough Canadians are crying to become the 51st state.
I'm of the mind that enough of our US trade flow is either 1) resistent to tariffs because they're already so much cheaper than alternatives that the Americans will just keep buying them even at the increased prices or 2) Can be re routed internationally to different customers over a bit of time (6-12 months) in large enough volumes that the worst of the economic pain is avoided. Companies super dependent on cross border flows will go away, new companies in their place who are better at exporting internationally will take their place. We may have to do some QE to pay for some internal programs and devalue the dollar a bit along the way vs the Euro until we find our feet.
