Hay ramya kumari, what Manpreet & Ananda Mahalingam say is correct. First understand the gist of the problem and talk. How can US play in Pakistan's politics? As someone rightly questioned, will the US accept if another country says that only this man should be President or that?
Already US is in danger for its attitude of interfering in other countries' internal matters. If US continues like this.....equal and opposite force will hit US in another form.
Ultimately, the affected is the innocent people with wars and bombs.
