What do Obama, Trump and Biden all have in common? As president, all three gave the order to take out significant figureheads in the world's most dangerous terrorism organisations. But they announced it in very different ways.
Obama was famously at the White House Correspondent's Dinner, gleefully roasting Donald Trump from the podium, having just given the order for troops to go into Pakistan on a covert mission to capture and kill Osama Bin Laden, the founder of Al Qaeda and mastermind of the 9/11 attacks. He announced the successful strike the following day.
Under Trump's watch, American forces took out Abu Bakr Al-Baghdadi, the leader of ISIS, which had ravaged Syria and expanded its caliphate via affiliate groups into areas in Northern Africa and beyond.
On Monday, Biden announced that American forces had killed Ayman Al-Zawahiri, the Emir of Al Qaeda, a successor to Bin Laden, in a precision strike in Kabul. It was the first strike in Afghanistan since American forces pulled out of the country, in what was seen by many as a hamfisted exit that handed the country back to a despotic regime.
