US Sucessful in deal of their soldier with Taliban

US  has dealt with Taliban today for their one soldier who was in hands of Taliban.

In this deal they have agreed to set 5 Taliban of Afghan released. They have dealt successfully.

What is myth behind all this no one knows. Why America knees down in front on Taliban for one soldier.

They are setting free 5 Taliban same time. On the other side their stance is that they are against

terrorism. How they negotiated with Taliban for this deal.
