Pretty sure the wind doesn't care about what country the plane is from.

Seems to me it was either unavoidable or Canadian air traffic control shouldn't have let them land in those conditions.

Nothing to do with Trump or the FAA, as much as people would like it to be.

Never let a crisis go to waste I guess?

The FAA will actually fully investigate this as the issue COULD be due to pilot error or equipment failure. So it is still potentially an issue outside of the weather.

Do you have a source or are you pulling that from nowhere?

Because the NTSB helps investigates. And the host country leads the investigation.

And yes it could be anything, but most likely it was the bad weather.

If you're going to speculate, go for the most likely one.
