President Joe Biden has revealed that the United States gave all it could to the military forces of Afghanistan but it could not provide them the will to fight for the future.

This comes after the United States withdrew its troops from the country after the Taliban’s return to rule brought an end to almost 20 years of a US-led coalition’s presence in the country.

The Taliban declared victory on Sunday, forcing Afghan President Ashraf Ghani to flee after the collapse of his government collapsed.

Speaking on Monday after his return to the White House from the Camp David presidential retreat, Biden said that the “American troops cannot and should not be fighting in a war and dying in a war that Afghan forces are not willing to fight for themselves.

“We spent over a trillion dollars. We trained and equipped an Afghan military force of some 300,000 strong. Incredibly well equipped. A force larger in size than the militaries of many of our NATO allies. We gave them every tool they could need. We paid their salaries, provided for the maintenance of their air force, something the Taliban doesn’t have. Taliban does not have an air force. We provided close air support. We gave them every chance to determine their own future. What we could not provide them was the will to fight for that future.

“There are some very brave and capable Afghan special forces units and soldiers. But if Afghanistan is unable to mount any real resistance to the Taliban now, there is no chance that one year — one more year, five more years or 20 more years — that U.S. military boots on the ground would have made any difference.

“Here’s what I believe to my core: It is wrong to order American troops to step up when Afghanistan’s own armed forces would not. The political leaders of Afghanistan were unable to come together for the good of their people, unable to negotiate for the future of their country when the chips were down. They would never have done so while U.S. troops remained in Afghanistan bearing the brunt of the fighting for them. And our true strategic competitors, China and Russia, would love nothing more than the United States to continue to funnel billions of dollars in resources and attention into stabilizing Afghanistan indefinitely.

“When I hosted President Ghani and Chairman Abdullah at the White House in June, and again when I spoke by phone to Ghani in July, we had very frank conversations. We talked about how Afghanistan should prepare to fight their civil wars after the U.S. military departed. To clean up the corruption in government so the government could function for the Afghan people. We talked extensively about the need for Afghan leaders to unite politically. They failed to do any of that. I also urged them to engage in diplomacy, to seek a political settlement with the Taliban. This advice was flatly refused. Mr. Ghani insisted the Afghan forces would fight, but obviously he was wrong.”
