The Afghan President Ashraf Ghani has expressed concern over terrorist threats and backed the new US Strategy. <br/><br/>He was addressing the United Nations General Assembly yesterday in New York. Ghani said US President Donald Trump's new Afghan strategy sent a signal to Taliban guerrillas that they cannot win on the field and must negotiate peace. <br/><br/>He instead has sent thousands more troops to Afghanistan and pledged a tougher line on Pakistan, which has long faced US criticism for its intelligence services' ties with jihadists and for harboring terrorists.<br/><br/>Mr. Ghani said, Afghanistan now also have an opportunity for a dialogue with the neighbours on how to work together earnestly to eliminate terrorism and contain extremism. Mr. Ghani called upon Pakistan to engage with Afghanistan on a comprehensive state to state dialogue on peace, security and regional cooperation leading to prosperity.
