Former American businessman who killed bin Laden: A retreat from Afghanistan the most embarrassing loss

Former U.S. Navy engineer who killed Osama bin Laden called Joe Biden a disaster because of his decision to withdraw troops from Afghanistan and described the escalation of the crisis as the worst loss in American history”.

Retired ex-marines Robert O'Neill has issued a series of statuss in recent days criticising the Benen administration after the Taliban took over Afghanistan on the eve of the American Army's departure.

So the situation in Afghanistan is a disaster,” wrote O'Neill on Monday afternoon.

This is the worst loss in American history. Our most popular president has disappeared. Prove me wrong”

Afghanistan fell to Taliban within a few days, instead of the 30 to 90 days it predicted American intelligence analysts, undoing the two-decade-old benefits of American troops stationed in the country after 11 September 2001, writes the Daily Mail.

Extremist fighters made major advances across the country over the weekend before capture the capital Kabul on Sunday, prompting American officials to speed up the evacuation of US Embassy personnel, citizens and Afghan citizens abroad.

Biden took a challenging stance in a speech to the nation on Monday afternoon, where he acknowledged that the collapse of the Afghan government was faster than anticipated by the US, but insisted he stood behind his decision to withdraw troops.
