it could be Asad troops. we can see they are many crazy guys there too.
anyway who ever did it ... what stupid crazy people . anyway barrel bombing places that shows how Asad should deserve no respect. sadly my country supports him. and i am ashamed of this.
and believe me if Iranians could choose in Iran: there would be no troop in there or any support. Especially it is better to spend for good inside Iran instead of sponsoring militias.
Iran was put in a bad position with Syria. If they completely disowned Syria, then the country would be a haven for terrorists, and become like Libya without Gaddafi. Iran couldn't let this happen for two reasons. First of all, Iran is not a country to suddenly turn a blind eye on their ally and let it turn into chaos. Secondly, Iran would be hurt in the future from extremists like daesh.
From day 1, Iran said that all dialogue should involve Assad because if he is suddenly removed, there will be a vacuum, and this can create civil war. But initially, all anti-assad groups & countries were so excited about their project that they said that any condition for talks was to have Assad resign first. This was a stupid demand to make. And I also remember, the the Syria talks wouldn't even involve Iran.
However, this could have handled much better. If there was an honest concern for Syrians, then they should have involved Assad seriously in the talks, with both sides of debate being involved (that is, both Turkey AND Iran, both USA AND Russia and so on). They should then have planned for reforms, new elections, with international observers.
That's the problem with our region. Nations have very black & white attitudes towards their neighbors. In 2012,
"President Mohamed Morsi of Egypt on Wednesday warned the Syrian president, Bashar al-Assad, that “your time won’t be long,” In 2011,
"Turkey's prime minister said Tuesday that Syria's president must step down over the country's crackdown on dissent, ratcheting up the pressure on the increasingly isolated Bashar Assad.
And Iran would have supported pressure on Syria, if it was honest pressure, and not just an excuse to kick him out, and not care what happens to Syria. This is in 2011,
"Iran's foreign minister says he backs Syria's president but that the embattled Bashar al-Assad must pay heed to his citizenry's demands amid the country's instability, an Iranian news outlet reported on Saturday.
Semi-official Iranian Students News Agency quoted Iranian Foreign Minister Ali Akbar Salehi as saying that Syria should be more cautious and patient in its dealings with the citizenry."
In the same report,
"Salehi insisted that al-Assad should be supported and that "changing the regime in Syria is unconventional and is followed by an evil purpose."
Salehi also said this very important phrase back then,
“A vacuum in the Syrian regime would have an unpredictable impact on the region and its neighbors.”
This is critical. Qatar, Turkey, and Egypt did not care about the unpredictable impact.
Syria could have been handled much better, and I'm certain that Iran would have been willing to support a new phase for Syria.
