There's a saying in Dari, the Persian dialect spoken in Afghanistan, "Ajala kaare shaitan ast (Haste is Satan's work)". It appears, however, the Iranian regime has not heard it: the ink on the US-Afghan Strategic Partnership Agreement was hardly dry when Tehran launched a verbal attack.
On Sunday, Iranian Foreign Ministry Spokesperson Ramin Mehmanparast expressed concern that the Pact may destabilise the region and called on the US to withdraw from Afghanistan immediately. Today, news broke that Iran's Ambassador in Kabul had met the head of the Afghan Senate, Fazel Hadi Muslimyar, and other legislators, asking them not to approve the Pact. The ambassador, Abdul Fazl Zuhrawand reportedly called the agreement a threat to the interests of other countries in the region, such as Russia, China, and India, as well as Iran.
