Better for Iran (and Pakistan) that Iran goes for the J-10 and Su-35 and leaves Pakistan out of its Military designs. If Iran wants to cooperate with Pakistan, it should start by resolving outstanding political issues like anti-Pakistan militants and their sponsors operating on their territory.
We can imitate <Cooperation mechanism for law enforcement and security in Mekong waters>(China, Laos, Myanmar and Thailand signed on October 31, 2011). China, Pakistan, Iran and Afghanistan signed a security cooperation agreement to establish a four nation joint security and counter-terrorism force to cooperate in combating all illegal organizations(TTP, BLA, ISIS...) in the region.
PS: The four countries of the Mekong River jointly clear the Golden Triangle in only two years.
In 2013, Nuo Kang was extradited to China for execution. This marked the collapse of the major drug trafficking groups in the golden triangle.
At the same time, I suggest that:
Pakistan and Afghanistan shelve the issue of the Durand line for 50 years and negotiate the Durand line after 50 years.
The Taliban allowed Tajiks to enter the govt.
Pakistan allows Afghanistan to connect CEPC and use Gwadar Port.
China is promise to large-scale investment in Afghanistan.
Tajikistan allows Afghanistan to connect the B&R line and uses Tajikistan's water resources to open lithium mines.
In this way, the four countries will gain and lose something:
Iran has won the friendship between Afghanistan and Pakistan, eliminated terrorist organizations, obtained support for the Tajik people in Afghanistan, obtained Chinese investment and obtained a stable oil sales channel. Iran will lose its influence in parts of Pakistan.
Pakistan has won the friendship of Afghanistan and Iran, eliminated terrorist organizations, obtained a stable development environment and a stable source of oil. Pakistan will lose part of the friendship between Saudi Arabia and the Americans.
The Taliban have won the friendship of all neighboring countries, the stability of the regime, a large amount of investment, two north-south commercial channels and Indian Ocean ports. The Taliban will lose the reason to refuse Tajiks to enter the government.
China has gained a lot and made investment.
... not sure what you smoked, but you should stay away from that stuff, really.
