According to Lindsey Graham, Republican senator for South Carolina, the President has “abandoned” US allies. With the President insisting the current evacuation remains on course to end this month, Mr Graham warned another attack similar to 9/11 was now possible. In a ferocious attack on Mr Biden, the senator claimed the withdrawal from Afghanistan was the “most dishonourable thing a commander-in-chief has done in modern times”.

Amid the rapid take over of the country by the Taliban, Mr Graham warned radical Islamicist groups could now attack the US.

He told Fox News’ Hannity programme: “This is a dereliction of duty by the commander-in-chief.

“This makes it harder to fight future wars.

“Who’s going to help us in the future after we abandoned our friends in Afghanistan who fought bravely?

“And the likelihood of a 9/11 is through the roof now, because Al Qaeda and ISIS are coming after us.

“If you believe we’ve left Afghanistan and we’ve ended the war between the US and radical Islam, you’re a fool.

“They’re coming after us and Joe Biden has left us naked and blind in Afghanistan.”

In polling released on August 24, Mr Biden’s disapproval rating has surged to 47 percent, according to pollster Five Thirty Eight.

Despite chairing the meeting, the Prime Minister failed to press Mr Biden into a delay to the withdrawal of troops which is expected to be completed by August 31.

The Prime Minister said on Tuesday: “The number one condition we’re setting as G7 is that they have got to guarantee, right the way through, through 31 August and beyond, safe passage for those who want to come out.

“Some will say that they don’t accept that and some, I hope, will see the sense of that, because the G7 has very considerable leverage – economic, diplomatic and political.”

Despite many calling on the US to delay the withdrawal, Mr Biden said the evacuation operation was on course to be completed on time.

He said following the G7 summit: “The sooner we can finish, the better.

“Each day of operations brings added risk to our troops.
