If true, this report is a significant sign that the regime’s power has grown shaky. Using foreign troops with no native loyalties save to the leader that employs them is an age old practice of threatened leaders. The use of foreign troops would indicate that the Iranian regime no longer trusts it’s own native forces to suppress the people.
The current election squabble is clearly a power struggle within the ruling oligarchy. The people of Iran have grown increasingly dissatisfied with the oligarchy’s regime. One faction in the oligarchy has decided to deploy that dissatisfaction against its opposing faction. Regardless of who wins, the oligarchy will have lost membership. Once-powerful insiders will find themselves as outsiders.
Such a contracting oligarchy has fewer and fewer people it can trust within the military and security forces, so they resort to importing troops they can trust.
Things might be looking up.
