Others have written that the Commerce Department needs proof from Boeing that it has been severely harmed in financial terms and that Chapter 19 won't cut the mustard, so to speak. The U.S. trade rules would if applied fairly, reverse the initial politically charged 220%, possibly to zero. Because Boeing has a substantial backlog amounting to billions of dollars and is hardly a crippled company due to competition in the single aisle market, where it is absent. In the meantime, it is entirely possible that Delta might be forced to cancel the contract with Bombardier. The editorial fails to mention that the U.S. laws require proof of substantial harm, which Boeing is hardly in a position to supply. Of course that process could play out long enough to put Bombardier out of business if the Chinese are unwilling to buy it. Fat chance of that.
