For whatevever reason, when most people in these parts think
war they think this:
Let's invade and conquer some territory boys!
No.
War in the 21st century is going to mean long range (conventional) ballistic missiles and cruise missiles neutering a country's ability to make war.
Canada's aviation industry in particular is deeply enmeshed with the US defense industrial complex. You think China, Russia or whoever else wouldn't launch long range missiles at a Canadian factory producing aircraft for US forces? It would take
years to rebuild a facility, nevermind the lost institutional knowledge which could never recover.
Of course they're going to blow it up. And by the way, that's exactly what the US would do to China. Target the factories... cut off their ability to produce more than what they already have.
This is why I said Canada needs to spend it's money on missile defense, long range missiles, air craft and mid-sized naval craft. Because if China or anybody else thinks they can cripple the US defense industry's ability to produce, they'll take that opportunity. A Canadian flag (or any flag) or Tennisance's myopic principles nobody cares about won't protect them.
