In this vieo the US President Donald Trump is seen saying that:
I have plans on Afghanistan that if I wanted to win that war Afghanistan would be wiped off the face of the earth it would be gone it would be over in literally in ten days and I don't want to do that I don't want to go that route so we're working with Pakistan and others to extricate ourselves ...
I am sure the USA has enough military might to do so - only one nuclear bomb is enough. But, I don't think he would be able to justify his decision in the US Congress and in the UN.
Is Trump able to wipe Afghanistan off the face of the earth by the unilateral decisions?
