Peace talks between Pakistan and Afghanistan in Istanbul have collapsed without agreement after three days of tense negotiations, leaving the border poised for renewed clashes. Negotiations, facilitated by Turkey and Qatar following deadly October border exchanges, broke down over mutual accusations. Pakistan admitted its drone strikes in Kabul stemmed from a deal with a third country, further complicating dialogue. As U.S. President Donald Trump pledged to push for rapid crisis resolution, both sides remain mobilized and the risk of a fresh military escalation on the Durand Line remains high.
