While Boeing may be too important to the U.S. for the U.S. government to let it fail, it will need to resume sales in places like Canada, the E.U., Japan, etc. etc. I think it is safe to say that their overseas sales are in jeapardy. Almost half of Boeing's sales are non-U.S.: https://www.statista.com/statistics/680130/revenue-of-boeing...

Note that this is FY2019, after losing 737MAX sales. If they are without a direct competitor to the Airbus A320 for years, it will be a big hit, not least because several Boeing-only airlines will be forced to start buying Airbus.

If it is 'too nationalist' to fail, shouldn't it be nationalized?

Boeing are poised to acquire Embraer: https://www.reuters.com/article/us-embraer-m-a-boeing/boeing...

It should be disallowed. It's more anti-competitive conglomeration, and risks the contagion of corruption.

Don't expect it to blocked under our current president. Bolsonaro is basically a Bazilian Trump.

Wasn’t the a ton of whining from the US when airbus bought bombardier?

Yes, there was - but now that Airbus has small planes, Boeing's lineup "needs" to expand to match, and buying a smaller manufacturer is the easiest way to do that.
