Don't talk about State control when the whole world knows that Israel has been repeatedly using Iran as a field for it's adventure sport... Picking off your Nuclear scientists at will. There seem to be rogue elements amongst Iranian forces who either carry out misadventures at behest of others or simply give cover to miscreants. Remember some years back after warnings from Pakistan, an intruding Iranian spy drone was shot down by the PAF in middle of the night.
Recently after a cross border raid by terrorists from the Iranian soil, realising Pakistan's patience was wearing thin, an Iranian minister rushed to Islamabad.
There are many countries in the region who would like to see Iran getting punished so its in best interest of Iran to keep good relations with it's immediate neighbours.
