Assad's fall was the result of a policy of "tolerating enemies."

Kayhan wrote:
Tolerance with the enemy in the first few months of the 14th government has had instructive results. After the assassination of the martyr Ismail Haniyeh, who had come to Tehran to attend the inauguration ceremony of the Iranian president, the government, happy with the promise of Europe and the United States, tolerated the enemy and postponed the response to this crime, but the result was nothing but the assassination of the martyred Secretary General of the Lebanese Hezbollah, Sayyed Hassan Nasrallah.
Tolerance with the enemy this time, like the historical experiences of the past decades, will bring nothing but losses to Iran. The Western-oriented current behind these poems and slogans weakens the internal components of power and paves the way for the enemy's advance step by step. These days, the news of Syria is at the top of the news in the region and even the world, and it is possible that in the past months, there have been those who have prescribed the Westerners' version, and "tolerance with the enemies" was implemented in Syria until the last stage, leading to the fall of Damascus in 11 days.
