Lukashenko has never threatened anyone. He is popular with his people and US foreign policy should concern itself with other more urgent matters like islamic extremists instead of still trying to overthrow Russia to sieze her riches.
The White Russians are only trying to protect themselves. All they have to do is look west to Yugoslavia and see what the US did and no wonder they are scared and want to go into a union with Russia.
Maybe we ought to have an Arkansas Democracy Act ;)
