The Afghan Taliban Pakistan had received training, weapons and shelter in Pakistan throughout the two decades it spent fighting the US and NATO in Afghanistan.

Pakistan Army soldiers and terrorists from jihadi groups based in Pakistan had also fought and died alongside the Taliban while fighting against the US and NATO forces in Afghanistan.

In the past, several US Army officers including top generals have accused Pakistan of sabotaging the US war effort in Afghanistan. However, that did not deter the US government to pursue a policy of treating Pakistan as a valued ally in the so-called 'War on Terror'.

Now, accusations against Pakistan of supporting terrorism has re-surfaced at the highest levels of the US administration.

Accusing Pakistan of double-dealing, Democrat senator from New Jersey Robert Menendez on Tuesday said that the US mission failed in Afghanistan as Islamabad offered a safe haven to the Taliban even as its militants targetted and killed US troops.

"Islamabad offered a safe haven to the Taliban even as its militants targetted and killed US troops. We need to have a serious conversation with the Pakistani Government in our path forward," said Senator Menendez, who was chairing the US Senate Committee on Foreign Relations. 

The senator, who is chairing a hearing of US Senate Committee on Foreign Relations on ambassadorial nominations to Pakistan, India and Germany, further said, "As I told this committee last month, the failure of our mission in Afghanistan was due, in a small part, to years of Pakistani double-dealing."

He also welcomed the nomination of Donald Armin Blome as US Ambassador to Pakistan.

"We welcome your (Donald Armin Blome as US Ambassador to Pakistan) nomination at this particularly challenging moment in US-Pakistan bilateral relationship," said the Democrat senator.

Further, Menendez welcomed the nomination of Eric Garcetti, as US Ambassador to India.

"As a member of Quad, alongside US-Japan-Australia, India is playing a greater role in helping maintain free and open Indo-Pacific. In September, Biden administration hosted 1st-ever in-person Quad Summit," said Menendez.
