[MCU] Where was everyone else at the Battle of Wakanda?

The only ones at Wakanda were wakandans and the Avengers.  Where were the militaries of the rest of the world?  Thanos is an existential threat to all of humanity.  His troops just made a mess in Manhattan and Edinburgh.  You'd think You'd at least get fighter fly overs or a few Jericho missiles hitting Thanos' troops.  Did no other country see the ships entering Earths atmosphere and heading to Africa?  Did T'Challa tell the US UK and anyone else that had military assets in the area to stay out?  If so how would his people feel about that?  Heck the Helicarrier would hae been nice although that can't move that quickly.

It all happened incredibly quick. If you noticed in the post credit scene, fury and hill get notice of contact in wakanda and then people start vanishing. And they’re the kind of people who know things before other people know things and it went too quick for them to even know what happened. And from the looks of it, they were in New York, probably to check out the site where the event there had taken place. It’s literally like a five minute battle before Thanos teleports in, shits on them, and snaps.
