Iran would be seriously concerned if it got double crossed by India..because Iran despite its all differences with Pakistan has held a common ground against terrorism in Sistan-Balochistan region and the last thing Iran wants is Pakistan parting ways and tilting balance towards Arabs who would be more than happy to give iran its own "yemen" while sheltering Pakistan from all diplomatic fallout..
Any self respecting country would be irked if a third used them as a mule against a neighbour..and in case of Iran..this matter only gets more sensitive..and Rouhani government wants good economic and political ties with Pakistan...it would be even less tolerant to Indian manipulation...
