how has Pakistan responded to accusations of supporting terrorism?

 Pakistan has rejected accusations of supporting terrorist groups. According to the Country Reports on Terrorism 2021 by the US State Department, Pakistan took steps in 2021 to counter terror financing and to restrain some India-focused militant groups. Pakistan reviewed and revised its 2015 National Action Plan (NAP) to counter terrorism, reducing the NAP from a 20-point plan to 14 key points, but made meager progress on the most difficult aspects, specifically its pledge to dismantle all terrorist organizations without delay or discrimination. 

Pakistan experienced significant terrorist activity in 2021, with major terrorist groups that focused on conducting attacks in Pakistan including TTP, the Balochistan Liberation Army (BLA), and ISIS-K. Separatist militant groups conducted terrorist attacks against varied targets in Balochistan and Sindh provinces[1].
