Why there’s even a dropdown to begin with

Maybe there was, and it was quickly dismissed.

That is what can be called a UX bug with huge seriously consequences. Luckily was not the other way around. Look men there is nuclear Weapon coming! Don't worry is just a test.

so it seems the the button was actually small

I think the actual point is that the target coordinates are not verified, but that ta$ty email address data is checked...

This is the ultimate Internet of Shit.

For once, I am happy to hear this explanation - now we "know" it was not the North Koreans :-)
