John Bolton, former US national security adviser, claimed Thursday that foreign terrorists have returned to Afghanistan and that the United States should not be supplying assistance to the Islamic Emirate.

Speaking in an interview with Newsmax TV channel, Bolton criticized the agreement of the Donald Trump administration with the Islamic Emirate, saying that they excluded a legitimate government in Afghanistan and while it was clear that the Islamic Emirate would not honor to its commitments, they cut a deal with it.

Bolton added that the decision to withdraw from Afghanistan was “catastrophic” and the Biden administration failed to implement it properly.

“Foreign terrorist fighters returned to Afghanistan and have begun launching terrorist attacks in Europe, in the Middle East, they attempted an attack against three Taylor Swift concerts this past weekend,” he said.

Bolton, who has also served as the US ambassador to the United Nations, told Newsmax that the first thing the US should do is isolate the Islamic Emirate.

“We should not be supplying any American assistance directly or indirectly, at least theoretically. We’re not doing it. We’re not giving the Taliban (IEA) government resources.”

“But it appears from a lot of reports that we’re still funding agencies that are aiding the Taliban (IEA) directly, so that our share of a typical U.N. assessed budget is 22%. I think this is really something Congress needs to look into further,” he said.

Bolton said the IEA is now hosting cells like Daesh and al-Qaeda that can threaten the country and become a “refuge for terrorists.”

The Islamic Emirate has previously denied the presence of terrorist groups in Afghanistan and emphasized that it will not allow Afghanistan’s soil to be used against other countries.

The Islamic Emirate has also rejected benefiting from the foreign humanitarian aid for Afghanistan.
