That's a good point. Perhaps globalization alone only marginally reduces the risk and it's the combination of globalization + trust (or at least not mistrust)

That's a good point. Perhaps globalization alone only marginally reduces the risk and it's the combination of globalization + trust (or at least not mistrust) that reduces the likelihood of war. If that's the case then the US government's efforts to take supplies away from some of our closest allies is even more dangerous and short-sighted than I initially thought. A month ago I would have said a mask factory in Canada vs. US is nearly equal in terms of national security because Canada could be trusted to help in a time of crisis. I'm sure many Canadians felt the same way. Now I'm not so sure that's true and I certainly don't blame the Canadians.
