I would currently be very afraid flying to the USA for a multitude of reasons. It doesn't help that I'm afraid of flying.
As for not falling out of the sky or hitting other aircraft, I think the U.S. still has the safest airspace. If you're referring to immigration/law/customs/etc, I can't help you there.
Even flying (commercially?) in other countries is still probably safer than driving.
Air travel is insanely safe, even in the shittiest countries.
you only hear about the dozen or so crashes every year. You don't hear about the 30-40 million other flights that don't have issues in a year.
