A good breakdown of the incoherence of the "secondary tariffs" threat. Of course, incoherence won't necessarily stop this administration from trying it, but it's very hard to see it getting turned into a workable policy if China or India calls the bluff. Is Trump really going to blow up all trade with China indefinitely if one refiner buys one shipment of Russian oil?
